Computer Simulation of Intake and Exhaust Manifold Flow and Heat Transfer

Modeling of unsteady two-phase reactive flow in porous beds of propellant

A numerical model of a pulse combustor has been developed to simulate the nonlinear wave motion resulting from the periodic combustion process. The wave pattern is followed in time by integrating the unsteady, one-dimensional equations of continuity, momentum and energy for vairable-are geometry, including losses due to friction and heat transfer. The resulting periodic wave pattern is governed by the pulse combustor geometry, the fuel mixture, and the combustion and injection processes. The simplified pulse combustor used in in this paper coasists of a combustion chamber and tail pipe joined by a short transition section. The resulting periodic wave patern is governed by the pulse combustor geometry, the fuel mixture, and the combustion and injection processes.

The model for the combustion process is guided by experimentally obtained chemiluminescence measurem...
