Numerical Simulation of Oscillatory Convection in Low Prandtl Number Fluids Using Aqua Code cases proposed in the benchmark problems. The AQUA code is a general purpose code and designed for the transient analysis of incompressible flow problems. A set of conservation equations are differenced based on the porous body approach and solved numerically with the use of velocity-pressure relat

Pressure correction splitting methods for the computation of oscillatory free convection in low Pr fhese methods are combined with the pressure correction method in order to decouple the pressure computation from the velocity computation. The resulting pressure correction splitting methods are used to compute the (oscillatory) free convection of low Pr fluids in a long rectangular cavity.

Results are obtained for the cavity problem with aspect ratio A = 4 for the rigid-rigid (RR) case and the rigid-free (RF) case, for Pr equal to 0.0 and 0.015 on an equidistant 20×80 spatial grid.

In particular, a lot of research has been devoted to the oscillatory behaviour of metallic melts (low-Pr fluids) due to the very crucial impact of such flow oscillations on the quality of growing crystals, semi-conductors or metallic alloys, for adv

Numerical Simulation of Oscillatory Convection in Low Prandtl Number Fluids with the TURBIT CodeThe results for the largest Grashof number on the coarser grid differ from those on the finer grid. With the finer resolution stable oscillations are predicted for Pr = 0.015 with three large corotating vortices, and unstable oscillations are found with a delayed transition from three to two vortices with finally time-independent flow for Pr = 0.
