Investigate the Heat Exchanger Efficiency of Hydraulic Liquid by using the Beta Test Loop

The aim of this paper is to determine the performance of the heat exchanger system using the hydraulic fluid . Investigation of heat exchanger system efficiency has been done versus the flow rate on the BETA test loop. This system can be used for investigation the hydraulic thermal changing. The Sequences on this system consist of a heat exchanger circuit that serves as a heat degree reducing from the primary part to the secondary part .The test method is carried out by operating the heat exchanger system with some variations of fluid flow rate in the primary part. The efficiency of system has been determined by comparing the energy value in the primary inlet to the energy value taken out form outlet by a secondary. Obtained results indicates that the increasing of fluid flow rate in the primary part from 3.86×10-4 m3 /s to 8.23×10-4 m3 /s cause a reduction in the efficiency of the heat exchanger system of about 82% to 74%
