Supersaturation in the spontaneous formation of nuclei in water vapor by Adolf Sander( )

2 editions published in 1953 in English and held by 24 WorldCat member libraries worldwide

According to experience, a certain supersaturation is required for condensation of water vapor in the homogeneous phase; that is, for inception of the condensation, at a prescribed temperature, the water vapor partial pressure must lie above the saturation pressure. The condensation starts on so-called condensation nuclei. Solid or liquid suspended particles may serve as nuclei; these particles may either a priori be present in the gas phase (dust, soot), or may spontaneously be formed from the vapor molecules to be condensed themselves. Only the second case will be considered. Gas ions which facilitate the spontaneous formation of nuclei may be present or absent. The supersaturations necessary for spontaneous nucleus formation are in general considerable higher than those in the presence of suspended particles

The effect of turbulence on the flame velocity in gas mixtures by Gerhard Damköhler( Book )

2 editions published in 1947 in English and held by 5 WorldCat member libraries worldwide

The present report deals with the effect of turbulence on the propagation of the flame. Being based upon experiments with laminar as well as turbulent Bunsen flames, both the physico-chemical and the hydro-dynamical aspects of the problem are analyzed. A number of new deductions, interesting from the point of view of engine combustion and other very rapidly changing flame reactions, are made
Isentropic phase changes in dissociating gases and the method of sound dispersion for the investigation of homogeneous gas reactions with very high speed. (Conclusion) by Gerhard Damköhler( Book )

2 editions published in 1950 in English and held by 5 WorldCat member libraries worldwide

The analytical results of Part 1 are also applied to sound dispersion by friction and heat conduction, An irreversible change of momentum, energy, and type of particle corresponding to friction, heat conduction, and diffusion effects can appear both in the direction of the sound field and traverse to it. Longitudinal damping, the coupling of longitudinal damping and that due to chemical and physical changes, and coupling of diffusion and compositional changes are treated for a plane sound wave of infinite extent. The same principles are also applied to sound effects in cylindrical tubes. The limitations of the method are discussed in some detail
Isentropic phase changes in dissociating gases and the method of sound dispersion for the investigation of homogeneous gas reactions with very high speed by Gerhard Damköhler( Book )

1 edition published in 1950 in English and held by 4 WorldCat member libraries worldwide

In seeking to investigate kinetically those homogeneous gas reactions which proceed at very high speed or at very high temperature we are frequently led to the field of isentropic changes in state in dissociating gases, a field which as yet has received no detailed theoretical treatment
A new propellant combination for rockets, using a solid oxygen carrier and ammonia as fuels by Gerhard Damköhler( Book )

1 edition published in 1947 in English and held by 1 WorldCat member library worldwide

Production, properties and handling of nitrosyl perchlorate are discussed. Nitrosyl perchlorate, which is part of a rocket or jet propellant, is used in connection with ammonia as an oxidizing agent. It comes in solid form and frees 59.6 percent of oxygen in combustion. Ammonia is especially suited for this purpose, being produced on a large scale and at low cost
