Inlet velocity equation
WebbThere is only one nonzero velocity component that in the direction of °ow,v x. Thus,v y=v z=0. 3. Since, in comparison with their spacing, 2d, the plates extend for a very long distance in thezdirection, all locations in this direction appear essentially identical to … Webb7 jan. 2024 · Assume I have N=10 equations that get a Dirchlet BC and a last one gets a Neumann BC, so there are 11 in total. The Dirichlet BCs are defined in “BCDirichlet”, for simplicity just the numbers 1 to 10. The matrix h is an identity matrix for all Dirichlet BC except for the last one with a Neumann BC for which it is set 0.
