| Abstract | ||||
| The evaporative heat exchanger has numerous applications in transferring heat. In this research an experimental study of the heat and mass transfer has been conducted on an experimental evaporative heat exchanger. The study involves the effect of cold water mass flow rate, hot water inlet temperature, air flow rate, injection holes diameter and horizontal distance between injection holes on the heat transfer, overall heat transfer coefficient, effectiveness and mass transfer. The results obtained indicate an increase of heat and mass transfer with the increase of hot water flow rate, hot water inlet temperature, air flow rate and injection holes diameter. | ||||
