"TWO-PASS TUBE HEAT EXCHANGER"

VRGEOM shapemaker utility has been used here to create the
objects for the geometry of two-pass tube heat exchanger.

In the case presented the simulation of flow and conjugate
heat transfer has been carried out to provide detailed
information about velocity and temperature fields in the
shell and tube sides.

The case is aimed at calculation of flow and thermal fields
in a straight tubes attached upstream and downstream on a
180-degree bend in a cylindrical turning section underneath
of rectangular channel.

The cold stream flows in the shell side over the tubes and
cold stream is considered as tube side flow. The tubes have
conductive walls of finite thickness participating in heat
transfer.
