NUMERICAL INVESTIGATION OF COUNTER FLOW ISOSCELES RIGHT TRIANGULAR MICROCHANNEL HEAT EXCHANGER

Effectiveness of counter flow isosceles right triangular microchannel is calculated with different values of Reynolds number. The water is taken as working fluid for both hot and cold fluid. By using the single phase liquid flow the thermal performance of microchannel heat exchanger is analyze. By solving the energy, continuity, and momentum equations the results are achieved all the equations are solved in FLUENT 16.0. The heat transfer rate, effectiveness, total pressure drop, friction factor, and the hydraulic and thermal performance of the channel are calculated for Reynolds between 100 to 400. The results shows that effectiveness, friction factor, and performance index of microchannel heat exchanger are decreasing with increased values of Reynolds number, whereas the pressure drop and heat transfer rate are increasing as increased in Reynolds number
