DESIGN, FABRICATION & PERFORMANCE ANALYSIS OF A SHELL AND TUBE HEAT EXCHANGER

Abstract

Heat transfer instruction lessons have been a mainstay of the curricula of undergraduate and postgraduate programs in mechanical and chemical engineering disciplines at higher institutions worldwide. This paper presents the design and fabrication of a shell-and-tube heat exchanger (STHE) for laboratory experiments. We aim to demonstrate the merits of spiral-coiled heat exchangers compared to conventional parallel-type heat Exchangers. The heat exchanger consists of one tube and a 508 mm-long shell with a 101mm diameter. Then we intended to perform a calculation on the heat transfer Effectiveness. We aim to demonstrate the merits of the spiral-coiled heat exchanger compared to the conventional parallel-type heat exchanger. This study investigates the thermal performance of a shell and-tube heat exchanger with copper tubes. The system's effectiveness was determined to be 38%, with the hot fluid's initial temperature at 60°C and its final temperature at 45.6°C. Concurrently, the cooling water temperature rose from 20°C to 35.2°C over a heat exchange duration of 54 seconds. The results indicate a moderate heat transfer efficiency, highlighting the potential for optimization in future designs or operational adjustments.
