AN EXPERIMENTAL STUDY OF EXERGY IN A CORRUGATED PLATE HEAT EXCHANGER

In the present work an attempt has been made to investigate the performance of a 3 channel 1-1 pass, corrugated plate heat exchanger. The plates had sinusoidal wavy surfaces with corrugation angle of 450. Hot water at different inlet temperature ranging from 400C to 600C was made to flow in the central channel to get cooled by water in the outer channels. For hot and cold fluid, Reynolds number was in the range of 900 < Re > 1300. Performance was measured in parallel and counter flow arrangement. Exergy loss is calculated and it is found that exergy loss is more in parallel flow arrangement than in the counter flow arrangement.
