3-Dimensional Retarding Walls and Flow in Their Vicinity

Abstract

In this project, the regression of combusting surface of solid propellant in rocket motors is investigated by using a fully 3-dimensional method which is called the "Fast Marching Method (FMM)." The FMM is capable of following the surface regression under local rate variations by itself. However, the aim is to use a varying burn rate under the effects of pressure and velocity. Different flow solvers are coupled with the FMM. At each time step FMM will generate mesh files for the solver and obtain fluid properties and therefore the burn rate.
