Summary:

This video briefly reviews the solution to the partial differential equations governing a tubular heat exchanger (details in video [termedpEN] –modelling–, [termedpsolEN] –Laplace Transform solution in transfer function form–). Then, it simulates its step response to incremets of inlet temperature as well as increments of heating power. Simulations are carried out in two scenarios: first, one with longitudinal cooling due to conduction to the outside environment, and a second scenario with perfect thermal insulation.
