Abstract

Finite element simulations have been performed along side normal mode
analysis on the linear stability that examined the development of volumetrically
heated flow patterns in a horizontal layer controlled by the Prandtl number, Pr,
and the Grashof number, Gr. The fluid was bounded by an isothermal plane above an adiabatic plane. In the simulations performed here, a number of convective polygonal planforms occurred, as Gr increased above the critical Grashof number, Grc at Pr = 7, while roll structures were observed for Pr < 1 at 2Grc.
