Abstract :
The performance of liquid water in the
double layer microchannel has been analysed using
three-dimensional conjugate heat transfer analysis. The
effect of flow rate on the counter and parallel
arrangement of each fluid is studied for three different
lengths. Furthermore, cooling capability of liquid water
is compared at the same length with flow rate and
pumping power as governing parameters. The
performance of fluid was judged on the basis of
maximum temperature attained and minimum
temperature variations at the heated region. Interesting
results have been found showing the effect of specific
heat on the type of arrangement for liquid water with
similar observation for water for low Reynolds number
and relatively longer length. Among liquid water, above
certain pumping power use of liquid water is found to be
favourable for a shorter length of the double layer
microchannel. Furthermore, the range of flow rate and
pumping power showing superior performance with
water was found to increase with the length.
