A method to determine the temperature field in a typical tubesheet ligament is developed. Using a numerical example, it is shown that, contrary to the common belief, a temperature gradient may exist throughout the thickness of the tubesheet in heat exchangers operating under “typical” conditions. Such thermal gradients can have significant influence on the exchanger’s thermal and mechanical performance. The solution is developed with an eye to its suitability as a design tool.
