Pattern competition in volumetricaly heated fluids

Cartland-Glover, Gregory, Fujimura, Kaoru and Generalis, Sotos (2012). Pattern competition in volumetricaly heated fluids. IN: Proceedings, 5th Chaotic Modeling and Simulation International Conference, 12 – 15 June 2012, Athens Greece. UNSPECIFIED.


Finite element simulations have been performed along side Galerkin-type calculations 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.
