COMPARATIVE ANALYSIS OF TUBULAR HEAT EXCHANGER FOR VARYING TUBES & TEMPERATURE PROFILES USING HYPERWORKV-13.0

Abstract

Heat exchanger keeps an important place in the industries like electric power generation, oil refining, chemical engineering etc. The study presents the linear static-steady thermal analysis of simple tubular type heat exchanger for different no of tubes with varying temperatures ranges. 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 pipes used. In this paper an attempt is made to model and analyze the comparatives study for three temperature profiles: Grid & Gradient temperature and element flux. This paper concludes that as the no. of pipes are increased the linearity increases for different temperature profiles. Whereas the rise percentage in the heat flow with respect to lesser no of pipes is negligible (4 to 10 degree Celsius).With respect to fewer pipes, geometrical area is increased as no of pipes are increased thereby increasing cost of manufacturing. The pictorial representations of simulated results reveals towards the higher level of linearity in case of more no of pipes for the steady state linear-thermal analysis.
