An Implicit Pressure Velocity Algorithm Applied to Oscillatory Convection in Low Prandtl Fluidined from a control volume staggered grid discretization with forward time centered space scheme. The transition to periodic oscillations is observed as the Grashof number increases from 10,000 to 50,000 and the dynamic properties are pointed out.

Book 1990n many fields of science and technology. 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 advanced tech

Buoyancy-driven oscillatory flows in shallow cavities filled with low-Prandtl number fluidsree (R-F) horizontal walls. Selected samples of results are given for the supercritical regimes. An hysteresis regime is found in the R-R cases, at Pr=0 and at Pr=0.015 for conducting horizontal walls, in narrow ranges of Grashof numbers.

Numerical Simulation of Oscillatory Convection in Low Prandtl Number Fluids Using Aqua Codelems. A set of conservation equations are differenced based on the porous body approach and solved numerically with the use of velocity-pressure relationship. The numerical scheme employed in the code has second order accuracy in both time and space. The results of both mandatory case A, B and recommended case C., D are presented.

Influence of Thermocapillarity on the Oscillatory Convection in Low Pr Fluidsot be neglected in experiments, like in molten gallium. The influence of thermocapillarity on the onset of oscillatory convection and the flow patterns of supercritical oscillatory states are discussed.

A Comparison of Velocity-Vorticity and Stream Function-Vorticity Formulations for Pr=0e of a rigid-rigid cavity with . = 0. A uniform mesh of 41 × 161 was used in both formulations. The velocity-vorticity method predicts more accurate velocity components but at a higher computational cost.

A Finite-Difference Method with Direct Solvers for Thermally-Driven Cavity Problemsstigate two cases with rigid and free-surface upper boundaries. For each of these cases, the effects of Grashof number is investigated for low Prandtl number fluids, namely Pr = 0 (conduction limit) and Pr = 0.015. The numerical results indicate the onset of oscillatory flow as well as some sudden transitions at higher Grashof numbers.
