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.
