Performance analysis of shell and tube heat exchanger under varying tube layouts baffle cut number of baffles

Abstract

The transfer of heat to and from process fluids is significant among the most basic unit operations in the preparing industries. Heat exchangers are gadgets that encourage efficient heat transfer between two mediums. In this manner the temperature distribution of the mediums can be changed when they are in direct or indirect contact. They can transfer heat between a liquid and a gas (e.g., a liquid to air heat exchanger) or two gases (e.g., an air to air heat exchanger), or they can work as a liquid to liquid heat exchanger. They, in this manner, form indispensable and inescapable equipment in an extensive variety of industries such as power generation, food processing, refrigeration, desalination, air conditioning, automobiles and electronics cooling. An extensive variety of heat exchangers are available in the market to take into account the requirements of various industries, similar to shell and tube heat exchangers, double pipe heat exchangers, plate type heat exchangers and spiral heat exchangers and so on. Based on the process requirements, the type of fluid, its phase, operating temperature, density, viscosity, pressure, chemical composition and various other thermodynamic properties, the appropriate type and size of the heat exchanger can be chosen. Heat exchangers are portrayed based on their capacity to accomplish greatest conceivable heat transfer coefficients inside their operating range of variables. This can be accomplished by compelling both the fluids at the greatest conceivable mass flow rates and likewise by providing hot fluid at higher temperatures. As a general guideline, multiplying the mass flow rate of the fluids may decrease the underlying cost significantly, however it will build the newlinepumping power requirements by a factor of around eight. newline newline
