TRANSITION TO UNSTEADINESS IN THREE DIMENSIONAL LOW PRANDTL NATURAL CONVECTION
Resumo
A numerical study of the unsteady natural convection
of low Prandtl number (Pr) fluids in a cubic cavity
is undertaken. A time accurate and robust marching
scheme has been used to study the transition to unsteadiness
over a range of Grashof numbers (Gr). The
results of three-dimensional computations are compared
to previously obtained two-dimensional findings
for Prandtl number 0.001 and several Gr around 106 .
