Original abstract
In multiphysics simulation are often used characteristics of measured component and simplified to speed up a process of solving a complex task. A cooling simulation relies on characteristics of a heat exchangers to solve heat transfer problem. It is common practice to use one temperature difference to obtain this characteristic. When the heat exchanger is measured at multiple temperature differences there is possibility to enhance the internal routine used in GT-Suite to eliminate an error caused by fitting one set of coefficients used in Nusselt number computation. This way the measured and computed model better fit to each other and increase accuracy of computing model.
