| Summary: | This paper presents variation of overall d
imensionless heat transfer rate
against
dimensionless tubes spacing, fins density,
Reynolds number for in
-
line configuration.
Influence of Reynolds number on the predicted and experimental results of
dimensionless pumping power minimization for with respect to the dimensionless fins
density for several tube
–
to
–
tube spacing also investiga
ted.
The experiments were
conducted at a flat tube in the flow direction, and Reynolds number based on the
hydraulic diameter (
Re
Dh
) was considered.
The dimensionless overall heat transfer rate
is always increases with an increase of the Reynolds number.
The dimensionless fins
spacing effect on the dimensionless overall heat transfer rate increase is noticeable at
high Reynolds numbers.
The dimensionless pumping power
increases with increasing
response
Reynolds numbers for dimensionless tubes spacing and d
imensionless fins
density. The dimensionless pumping power decreased with increase of
dimensionless
fin density |
