Abstract
Heat exchangers are essential in many sectors, such as paper, chemicals, oil, processing, petroleum refining, and power plants. The need for efficient heat exchangers is a result of their high efficiency and environmental concerns. Heat transfer improvement is crucial for increasing efficiency since it enables smaller heat exchanger sizes and a high heat transfer rate with less space needed. Using plain tube and plain twisted tape inserts, counterflow heat exchangers enhance the transfer of heat properties of concentric tube heat exchangers. To improve heat transmission & generate turbulence, twisted tape inserts are used to concentric tube heat exchangers. A variety of techniques, such adding fins or raising fluid velocity, can be tested to see which improves heat transmission in small heat exchangers the most.
