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 ...

A perspective on computational aerothermodynamics: Current modeling difficulties
Author(s): Candler, Graham V.
Abstract: Future hypersonic vehicles are going to be designed largely with computational fluid dynamic methods based on appropriate physical models. The question on how much of this design process can be completed with the present ...

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 ...
