Double Pipe Heat Exchanger Modelling - COMSOL Uses in Undergraduate Education

L. Desgrosseilliers, and D. Groulx
Mechanical Engineering
Dalhousie University
Halifax, NS
Canada

A cornerstone of Chemical and Mechanical Engineering undergraduate programs the world over is the experimental and theoretical study of heat exchange. Graduating engineering students gain some appreciation in their lab course by comparing empirical correlations combined with the thermodynamics of heat exchange with the real operation of a counter-current, double pipe, single-phase heat exchanger.
