Abstract
In this work, an experimental setup for trio tube heat exchanger is designed and fabricated. The experimental setup is comprises of aluminum (inner tube 12.7 mm) and copper (intermediate tube 25.4 mm) and GI tube (outer tube 38.1 mm). The effective length of the heat exchanger is 2.1 m. For the hot fluid, a 2000 W capacity immersion heater was used to raise the temperature of the water. In this experimental setup, heat can be transferred between three liquids. Which is it’sspecial competence over the double tube heat exchanger. Three different flow arrangements can be maintained in the heat exchanger; N-H-C, C-H-C and C-H-N. The performance of the experimental setup was initially tested for water. The measurements were taken at 50 ℃ temperature of hot water and 30℃ of the other two water streams at the inlet. The experiments were conducted for counter flow arrangements of fluid streams so that the performance of the heat exchanger can be checked at the maximum amount of heat extraction from hot water. The temperature variation along the length of the heat exchanger was analyzed, the graphs are in good agreement with the standard graphs.
