We also define the Laplacian in this section and give a version of the heat equation for two or three dimensional situations.3 . The convention in shell-and-tube heat exchangers is as follows: T 1: inlet temperature of the shell-side (or hot) fluid . T 2: exit temperature of the shell-side (or hot) fluid t 1: inlet temperature of the tube-side (or cold) fluid . t 2: exit temperature of the tube-side (or cold) fluid Thus,
