Abstract:

An inviscid, unsteady, chemically reacting flow model has been developed which illustrates the principal features of the blast field generated by ignition of a rocket motor in immediate proximity of the ground or sea surface. The system of governing equations and solution algorithm are outlined, and several numerical examples are discussed. An asymptotic solution to the flow field produced by the blast wave is discussed and compared with the present numerical solutions. Correlation of the asymptotic solutions for various time steps and for various sources of high pressure propellant gases is demonstrated. Extension of the model to include turbulent mixing and more complete chemical kinetics is recommended. Author
