How can I make optimum use of the installation space in a shell-and-tube heat exchanger? How can I find out whether many tubes with small diameters or fewer tubes with larger diameters are better? With which pipe mirror can I achieve the optimum result?

Project Objective:

Development of a mathematical optimization algorithm that maximizes the heat transfer surface in a shell-and-tube heat exchanger under consideration of manufacturing boundary conditions.


Project manager, heat exchanger manufacturer


When designing a shell-and-tube heat exchanger, similar questions always arise. A central question is: Which pipe diameter is optimal? What is the best way to arrange the tubes to achieve the maximum effect?


Our client wanted a permanent, generic solution to this question. He has therefore received from us a mathematical optimization algorithm with which he can answer this question in five minutes.

The starting point is a defined shell, into which the tube bundle must fit. He must also define minimum distances, e.g. from the wall. He can then define pipes that are suitable for him, e.g. 20×2 or 10×1. The software then creates different pipe mirrors and outputs the surfaces. Of course, the pipe mirror is also output graphically with all relevant labels.

With this result he can go into the thermal design and e.g. evaluate the costs.
