SPIKE
Navier-Stokes multiblock implicit/explicit 3D body fitted co-ordinate scheme. Approximate Riemann solver utilising a TVD scheme using a point implicit time marching algorithm or line-implicit Gauss-Seidel relaxation scheme. Baldwin Lomax and k-e turbulence models. Mesh generation is by Finite Element style generator. Output is represented using any basic F.E. post processor.
Used for complex aerodynamic configurations for example transonic/supersonic spinning artillery shell solutions, planetary re-entry aerodynamics and general compressible flow problems. Deals with shocks and calculates heat transfer to surfaces.
TINA
Thermochemical Implicit Non-Equilibrium Algorithm. Non-equilibrium version of SPIKE with additional models for thermal and chemical non-equilibrium, the latter for homogeneous and non-homogeneous systems.
This code is primarily for complex aerodynamic and aerothermodynamic problems where full kinetics including catalytic and material ablation surface effects are required. It is used in high temperature applications where thermal non-equilibrium is important e.g. behind strong shocks for entry vehicle studies, and in hot expanding flows such as rocket nozzles and plumes. In the latter case the code employs a number of particulate/droplet chemistry models in its fully coupled two phase routines.
FINS
3D Fully Implicit Navier-Stokes Code - applicable to incompressible flows. Uses same grid package as TINA/SPIKE.
Used for low speed flow applications such as fires, flow over vehicles and in ducting. Full implicit algorithm is very fast compared to point and line implicit solvers.
