A numerical approach to improve the flow model of an electrostatic precipitator by Shah Haque( )

1 edition published in 2008 in Undetermined and held by 1 WorldCat member library worldwide

This paper presents a numerical approach to develop an accurate Computational Fluid Dynamics (CFD) model for an electrostatic precipitator (ESP). The flow simulation was performed by using the CFD code FLUENT. Numerical calculations for the air flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modelled using the realizable k-e turbulence model. Simulation with uniform (ideal) velocity profile is compared with that with measured (real) velocity profile at the inlet boundary. The model developed by using the measured velocity profile at its inlet boundary showed more reliable simulation results

Review of cyber-physical system in healthcare by Shah Haque( )

in English and held by 1 WorldCat member library worldwide

Cyber-physical system (CPS) is an integration of physical processes with computation and communication. It has the ability to add more intelligence to social life. Wireless sensor networks (WSN) can be a vital part of CPS as strong sensing capability is one of the major driving factors for CPS applications. CPS is still considered to be a nascent technology, and there are many challenges yet to be addressed. A few CPS applications in healthcare have been proposed to date, and they lack the flexibility of technology integration, such as integration of computing resources with sensor networks. This paper presents a survey of CPS in healthcare applications that have been proposed to date by academia as well as industry. A comprehensive taxonomy is also provided that characterizes and classifies different components and methods that are required for the application of CPS in healthcare. The taxonomy not only highlights the similarities and differences of the state-of-the-art technologies utilized in CPS for healthcare from the perspective of WSN and Cloud Computing but also identifies the areas that require further research. It is expected that this taxonomy and its mapping to relevant systems will be highly useful for further development of CPS for healthcare
Modelling and simulation of particle trajectory inside an electrostatic precipitator by Shah Haque( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

This paper presents a Computational Fluid Dynamics (CFD) model for particle trajectory inside a wire-plate electrostatic precipitator (ESP). The turbulent gas flow and the particlemotion under electrostatic forces were modelled using CFD code FLUENT. Reynolds averaged Navier-Stokes equations were solved numerically for predicting the gas flow. The turbulence was modelled using the realizable k-Sf turbulence model. The effect of electric field had been captured by adding a source term in the momentum equation. This additional source term was obtained by solving a coupled system of the electric field and charge transport equations. The particle phase was simulated by using Discrete Phase Model (DPM). The results of the simulation showed that particle trajectory depends on the size of the particle diameter. The larger the diameter, the more efficient was the particle collection due to the higher particle charging. This study gives an insight into the particle dynamics and its collection inside any industrial ESP
A numerical model of an electrostatic precipitator by Shah Haque( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

This paper presents a Computational Fluid Dynamics (CFD) model for a wire-plate electrostatic precipitator (ESP). The turbulent gas flow and the particle motion under electrostatic forces are modelled using the CFD code FLUENT. Numerical calculations for the gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modelled using the k-Sf turbulence model. An additional source term is added to the gas flow equation to capture the effect of electric field. This additional source term is obtained by solving a coupled system of the electric field and charge transport equations. The particle phase is simulated by using Discrete Phase Model (DPM). The results of the simulation are presented showing the particle trajectory inside the ESP under the influence of both aerodynamic and electrostatic forces. The simulated results have been validated by the established data. The model developed is useful to gain insight into the particle collection phenomena that takes place inside an industrial ESP
Fine particulate emission control by optimizing process parameters of an electrostatic precipitator by Shah Haque( )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

This paper presents a numerical model of a wire-plate electrostatic precipitator (ESP) for analysing its fine particulate collection behaviour. Computational fluid dynamics (CFD) code FLUENT is used to solve the two-dimensional NavierStokes equations for the gas flow and the realizable k-Sf turbulence model for the turbulence. The effect of electric field has been captured by adding a source term in the momentum equation. This additional source term is obtained by solving a coupled system of the electric field and charge transport equations. The particle phase is simulated by using Discrete Phase Model (DPM). The results of the simulation revealed that the particle collection and its movement depend not only on the size of the particle but also on the velocity of the gas flow and the electric potential applied at the discharge electrodes
Flow distribution inside an electrostatic precipitator : effects of uniform and variable porosity of perforated plate by Shah Haque( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

This paper presents a numerical flow model applied to a 3D geometry of an electrostatic precipitator (ESP). The flow simulation is performed by using the computational fluid dynamics (CFD) code FLUENT. Realizable k-Sf model for turbulence condition inside the ESP is applied. In the simulation, the perforated plates are modeled as thin porous media of finite thickness with directional permeability. Perforated plates with both uniform porosity and variable porosity are considered for simulation. The results of the simulation are discussed and compared with on-site measured data supplied by the local power plant. The simulated results show reasonable agreement with the measured data
Storage node based routing protocol for wireless sensor networks by Shah Haque( )

in English and held by 1 WorldCat member library worldwide

Efficient routing is a key concern for the execution of high performance query processing in Wireless Sensor Networks (WSN). Existing routing protocols lack the efficiency in terms of energy consumption, accuracy and timing response. Data storage and processing constraints in sensor nodes also hinder the efficient and timely response in various applications, especially in healthcare, where, many vital data are collected from the patients using wireless devices. These data can be crucial for saving the patient's life. Thus, an efficient, accurate and fast routing protocol is of utmost importance in healthcare. Present routing protocols in hierarchical network protocols, the cluster heads are selected from general sensor nodes, however the storage and processing constraints perceive in the usual wireless biomedical sensors as the processing requires more energy consumption and the storage capacity is limited. In this paper we propose a novel routing protocol by utilizing Storage nodes. We evaluate and prove the feasibility of the proposed protocol through extensive simulations. Simulation results show that the protocol is more energy efficient, faster and data resilient compared to other techniques
False alarm detection in cyber-physical systems for healthcare applications by Shah Haque( )

in English and held by 1 WorldCat member library worldwide

Cyber-Physical System (CPS) is an integration of physical processes with computation and communication. CPS connects the virtual world with physical world. It has the ability to add more intelligence to social life. A CPS integrates physical devices, such as sensors and cameras, with cyber (or informational) components to form a situation-integrated analytical system that responds intelligently to dynamic changes in the real-world scenarios. Wireless Sensor Networks (WSN) can be a vital part of CPS as strong sensing capabilities can be one of the major driving factors for CPS applications. Still CPS is considered as a nascent technology and there are many challenges yet to be addressed. These challenges are often posed due to the complexity of communication, computation and the uncertainty of physical processes. CPS can have wide ranging applications, such as smart medical technology, assisted living, environmental control and traffic management. Unfortunately, no unified architecture for CPS has yet been developed, primarily due to variations among the applications. In CPS healthcare application, a wide range of medical sensors are used, however these sensors generate a large number of false alarms. These false alarms add confusion and reduce the efficiency of overall healthcare service. Although a few CPS healthcare architectures have been proposed for healthcare application they all lack of efficient false alarm detection. In this paper, a novel false alarm detection architecture is proposed in CPS for healthcare applications
