The 3D flow in a shell om imaginery heat exchanger is
simulated. The heat exchanger considered has two baffles
within the shell.
The self-steering local false-time under-relaxation
for the velocities is introduced by PLANTed codings for
sources as follows:
TYPE is PHASEM, VALue is SAME, CO, which is reciprocal
of DTFALS, is set to the local velocity vector magnitude
divided by smallest distance between walls of continuity
cell in question plus local diffusivities, i.e. kinematic
viscosities, divided by the smallest distance squarred.
Interesting variants include comparison of the rate of
convergence for conventional once-for-all under-ralaxations
and PLANTed ones for enul=0.0 and enul=1000 as for
NX*NY*NZ=5*3*8, and for NY=3 and NY=10 as for enul=0.0.
FLO1 = mass-flow rate of shell fluid
