DISPLAY
This case simulates a heat transfer by convection about
a single heated pipe which is described by a cylinder object.
The pipe allocates heat non-uniformly in the Z direction.
The pipe is cooled by a air flow of which moves
in the X direction from left to right.
The air flow is laminar. The Reynolds number equals 26.
The Prandtl number equals 0.7
Nusselt number calculated by the formula for a external cross
flow of a round pipe, located in depth of a pipe array,
Nu = 0.3*Re^0,6*Pr^1/3
equals 1.9.
The In-Form is used for the setting of a non-uniform heating
source per unit volume as
(SOURCE of TEM1 at PIPE is 1.e+5*ZG with VOLU)
