Abstract

The film condensation of refrigerant R-134a in circular (diameter 1 mm), triangular (side 1 mm), inverted triangular (side 1 mm), square ( side 0.5, 1, 2, 3, 5 mm), rectangular (sides 1x1.5 and 1.5x1 mm) are numerically studied through ANSYS Fluent 16.1. The effect of channel shape was investigated where the wall temperature is uniform with velocity inlet of vapor 3 ms-1 and vapor inlet temperature at 90oC. The results showed that The film thickness is grow gradually in 0-100 mm from inlet and then has not much change along 200 mm – outlet. Although the film thickness is generated in every microchannel and even the film generated is almost equally (except square with side 5 mm), the square channel come out with higher heat transfer coefficient than other channel shape.
