TALK=T;RUN(1,1) DISPLAY In-Form is used for specifyinhg non-uniform inlet, outlet and wall boundary conditions, for: steady laminar flow and heat transfer in a plane channel. ------> Wall velocity proportional to x //////////////////// North Wall /////////////////////// ------------------------------------------------------- parabolic -> outlet resistan$ ce mass-flux --> varies with velocity -> y value and constant ---------------------------------------------------- enthalpy //////////////////// South Wall /////////////////////// ^ y ------> Wall velocity proportional to x |-------> x-direction The inlet flow has a parabolic profile The outlet coefficient = A + B * sin[ pi *( y/yv]ast - 1/2 )] where A and B are constants, yvlast is channel width. North and south walls moved with velocity proportionally to longitudinal distance, x Their enthalpy is a piece-wise-linear function of x. South-wall boundary condition uses PATCH of SWALL type. North wall boundary condition uses PATCH of NORTH type and therefore need LAMWALL option. Solution should be symmetrical about channel centre plane.
