Flow-through boundary conditions for time-dependent, buoyancy-influenced flow simulations using low order finite elements
Technical Report
·
OSTI ID:5979547
Two methods are presented to extend the utility of outflow natural boundary conditions from isothermal flows to those in which an additional vertical pressure gradient, associated with buoyancy-influenced flows, is important. Each of these methods approximates the pressure contribution to the natural boundary conditions in a time-dependent way. The methods are derived and demonstrated in two-dimensions and the extension to three-dimensions is discussed.
