Thermal convection in square porous cavity under transverse oscillatory micro gravity field

Abstract

Two-dimensional thermal convection in saturated square porous cavity under transverse sinusoidal micro-gravity field, has been analyzed by solving mass and transient momentum and energy balance equations, using Darcy s law and Boussinesq's approximation. Isothermal boundary conditions are considered at the two vertical walls but at different temperatures and other two horizontal walls are adiabatic. Average Nusselt numbers are presented as a function of Darcy-Rayleigh number (Ramod) and dimensionless time. Thermally convective, transient nature of the flow field has also been presented for different Darcy-Rayleigh number (Ramod).
