Atmospheric dissociation will be appreciable in the neighbourhood of projectiles travelling at speeds greater than 2 km/sec. This introductory paper on possible effects of dissociation on the airflow, and hence on the drag, stability and aerodynamic heating of such projectiles, is intended mainly as a source of ideas for later, more comprehensive investigations. 

Mixing of homogeneous streams of dissociating air

The influence of nonequilibrium dissociation on the flow field in laminar mixing of homogeneous air flows is investigated by a perturbation method. The Mach, Prandtl, and Schmidt numbers are selected

The nature of the flow of a dissociating diatomic gas in a convergent-divergent supersonic nozzle is investigated by measuring the distribution of flow parameters along the nozzle. Two parameters are

Weak discontinuities in a thermally conducting ideal dissociating gas

After surveying the main features of a thermally conducting Lighthill-Clarke gas, the propagation speed of weak discontinuities through such a medium is determined. Then the growth equations of the

The flow of an ideal dissociating gas through a nearly conical nozzle is considered. The equations of one-dimensional motion are solved numerically assuming a simple rate equation together with a

Magnetohydrodynamics and its Application to Propulsion and Re-Entry

The first part of this paper is largely a review of some of the basic concepts of magnetohydrodynamics in the regime of continuum fluid mechanics. The acceleration of plasmas to high velocities by

Effect of heats of chemical reactions on turbulence in homogeneous gas mixtures

The effect of the heats of chemical reactions on the turbulence in a turbulent gas flow is considered. An example of the application of the obtained results to a dissociating polyatomic gas is given.

On the breakdown of acceleration waves in dissociating gas flows

The present paper is devoted to the study of characteristic solution in the neighbourhood of the leading frozen characteristics in dissociating gas flows. It is found that at the cusp of the envelope

Dissociation and Ionization in Sonoluminescence

An hydrodynamic model for single bubble sonoluminescence (SBSL) taking into account dissociation in diatomic gases and ionization in monoatomic ones is presented. Bubble inertial effects are neglec...

The nature of the non-equilibrium flow of strongly dissociating nitrogen has been investigated by a series of simulation calculations using non-equilibrium (finite rate) chemical reactions. These

Numerical simulation of non-equilibrium hypersonic flows with wall catalytic effects

The effect of surface catalysis on heat transfer for hypersonic flow past a hemispherical cylinder at a freestream Mach number of twelve and an altitude of 30.48 km was investigated by solving the
