This simulation models an extended area (cross-flow) heat exchanger. Use the switches for the pump and fan to turn them on/off. Drag the thermometer to change what it measures, and rotate the flow dial to change the flowrate setpoint. Scroll to zoom and drag the screen to pan.

This digital experiment was created in the Department of Chemical and Biological Engineering at University of Colorado Boulder for LearnChemE.com by Drew Smith under the direction of Professors David B. Thiessen and John L. Falconer. It was prepared with financial support from the National Science Foundation (DUE 2336987 and 2336988) and is based on an Extended Area Heat Exchanger experimental kit and accompanying worksheet protocol developed with separate support under NSF 1821578 led by Washington State University.
