Computational techniques for flows with finite-rate condensation
Author(s): Candler, Graham V.
Abstract: A computational method to simulate the inviscid two-dimensional flow of a two-phase fluid was developed. This computational technique treats the gas phase and each of a prescribed number of particle sizes as separate fluids ...

Simulation of ablation in Earth atmospheric entry
Author(s): Keenan, James A.; Candler, Graham V.
Abstract: The process of ablation for Earth atmospheric entry is simulated using a computational approach that allows thermo-chemical nonequilibrium of the flow field and ablation gases. The heat pulse into the heat shield is modeled. ...

Effects of vibrational nonequilibrium on axisymmetric hypersonic nozzle design
Author(s): Candler, Graham V.; Perkins, John N.
Abstract: A vibrational nonequilibrium Navier-Stokes computational algorithm is used to determine the flow conditions in several existing nozzles. Vibration freezes near the throat for typical stagnation conditions in these nozzles. ...

A numerical method for predicting hypersonic flowfields
Author(s): Maccormack, Robert W.; Candler, Graham V.
Abstract: The flow about a body traveling at hypersonic speed is energetic enough to cause the atmospheric gases to react chemically and reach states in thermal nonequilibrium. In this paper, a new procedure based on Gauss-Seidel line ...
