ABSTRACT:
In this paper fluid flow and heat transfer are modeled in
a corrugated 3D plate heat exchanger geometry with a
commercial computational fluid dynamics (CFD) program,
Fluent 6.1.22 (Fluent Inc., Lebanon), in order to find out the
most realistic heat transfer boundary conditions for a plate
heat exchanger. The built-in boundary conditions of Fluent
available for this case are Heat flux, Convection and
Constant wall temperature. The CFD models are verified
with correlations and experimental data obtained by a flat
plate test equipment of which parameters can be calculated
analytically.
Deficiencies are found in all the built-in heat transfer
boundary conditions. Heat transfer modeling with CFD in a
corrugated plate heat exchanger is problematic because of
the assumptions that have to be made when defining the
boundary conditions in the complex geometry. The values
of the computational parameters have spatial variations and
can not be defined explicitly. However, when compared to
the experimental correlations in the literature, the
Convection boundary condition gives the most realistic
results in the case of corrugated plate heat exchanger.
