Efficient preprocessing of complex geometries for CFD simulations

Anisotropic metric-based mesh adaptation for unsteady CFD simulations involving moving geometries

Validation of the Aerodynamic Loading on Basic Flying Disc Geometries Derived from CFD Simulations

The present study in spin stabilised disc aerodynamics builds on previous experimental wind tunnel work to broaden the knowledge base through CFD simulation without the necessity for high facility or time cost. The current experimental database from previous studies is extensive enough for sufficient validation to be conducted on known geometries. From there, the limitations of CFD studies for ...

Incorporating Diffusion in Complex Geometries into Stochastic Chemical Kinetics Simulations

A method is developed for incorporating diffusion of chemicals in complex geometries into stochastic chemical kinetics simulations. Systems are modeled using the reaction-diffusion master equation, with jump rates for diffusive motion between mesh cells calculated from the discretization weights of an embedded boundary method. Since diffusive jumps between cells are treated as first order react...

Flow Simulations on Cartesian Grids involving Complex Moving Geometries

We describe a method to solve the compressible time-dependent Euler equations using Cartesian grids for domains involving xed or moving geometries. We describe the concept of a mirror ow extrapolation of a given solution over a reeecting wall which may be curved or moving at a xed or varying speed. We use this mirror ow to develop a Cartesian grid method to treat the cells along a reeecting bou...

CFD Simulations of Pressure Drop in KATAPAK-S Structured Packing

KATAPAK-S is a type of structured catalytic packing, which is used in reactive distillation processes. The dry pressure drop characteristic (the pressure drop in the absence of liquid flow) is of significant importance for the investigation of process hydrodynamics. In this paper, the dry pressure drop within the catalyst packed channels of KATAPAK-S has been investigated using Computational Fl...
