Numerical simulation of radiation in high altitude solid propellant rocket plumes

Monte Carlo Simulation of Particle Radiation in High Altitude Solid Rocket Plumes (Invited)

Several recently developed numerical schemes are used in an integrated framework to simulate the plume flow from a representative solid propellant rocket at an altitude of 114 km. In nonequilibrium regions the gas is modeled using the direct simulation Monte Carlo method, while a particle simulation method based on a simplified approximation of the Boltmann equation is used in near-equilibrium ...

High Altitude Plume Simulations for a Solid Propellant Rocket

A simulation scheme is proposed for flowfield and radiation analysis of solid rocket exhaust plumes at high altitude. Several recently developed numerical procedures are used to determine properties of the gas and condensed phase Al2O3 particles, and spectrally resolved plume radiation calculations are performed using a Monte Carlo ray trace model. Simulations are run for a representative plume...

Acoustic-Mean Flow Interaction in Solid Propellant Rocket Motors

There are several sources for pressure oscillations in solid propellant rocket motors. Oscillatory flow field is one of them. Free shear layers in motor flow field cause vortex shedding. End edges of propellant grains and baffle edge in two-segmented motors are samples of such zones. These vortices move from their forming points and strike the field walls. The kinetic energy of vortices change ...
