Design And Heat Transfer Effect On Shell And Tube Heat Exchanger
Subject area: Science,Engineering and Technology · Area of research: Mechanical Engineering
Abstract
Heat exchanger is the equipment which is used to reduce temperature of one process fluid. Which is desired to cool, by transferring heat to another fluid which is desired to heat with or without inter-mixing the fluid or changing the physical state of the fluid. The main objective in any heat exchanger design is the estimation of minimum heat transfer area required for a given heat load, as it governs the overall cost of the heat exchanger. The design of shell and tube heat exchanger are included mechanical design and thermal design. The mechanical design includes the design of main shell under internal and external pressure drop, tube design, baffle design, etc. The thermal of shell and tube heat exchanger are involved evaluation of required effective surface area, number of tubes and finding out log mean temperature different. For evaluation of shell and tube heat exchanger, thermal performance and pressure drop are dependent on the path of fluid flow and types of baffles in different orientation respectively. The objective of the present work is to predict the variation of heat transfer rate, log mean temperature difference, heat transfer coefficient, and pressure drop to the shell and tube side with change in range of Reynolds number to different baffle orientations. The thermal model was developed using the effectiveness NTU method. The shell side and tube side overall heat transfer coefficient were determined using the Scider-Tate and Housen equation.
