DESIGN AND ANALYSIS OF TUBULAR HEAT EXCHANGER FOR VARYING TEMPERATURE PROFILES USING ALTAIR HYPERMESH
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 12
Abstract
This Paper deals with the heat transfer of shell and tube or simply tubular type heat exchanger for different no of tubes with varying temperatures. It provides a linear steady state thermal analysis which further be analyzed in analogy of structural parameters. The thermal stress and heat transfer induced is studied using Altair HYPERMESH HyperworkV13.0 simulating software at steady state boundary conditions. Heat exchanger is designed for analyzing heat transfer rate using air as a working medium for parallel flow justifying the phenomenon of convection within the shell and tubes used. Tubular exchangers are used primarily for liquid-to-liquid. An attempt is made in this paper is to the design of shell and tube heat exchangers by modeling & CFD analysis in Altair HYPERMESH using tube material as Aluminum, which is the best source of heat transfer and modeling procedure assembly of Shell and Tube is done using air as working medium. The thermal analysis of Shell and Tube heat exchangers is carried out by varying the temperature of inletting air. The geometrical modeling covers a shell containing five numbers of tubes with it. With the help of the simulating results, maximum & minimum temperature gradient ranges from 2.931 to 14.23kW/mm2 & 0.0 to 2.384E-07 kW/mm2 respectively. The maximum & minimum grid temperature ranges from 3.008E+15 to 15.04E+15 kW/ mm2 & -0.005157 to -0.02579kW/mm2respectively. The maximum & minimum element flux ranges from 6.947E+02 to 33.72E+02kW/mm2& 0.00 to 5.651E-05kW/mm2respectively. The pictorial representations of simulated results reveals towards the steady state linear thermal analysis.
