1D models of the thermohydraulic systems supported by CFD results and measured data

Abstract

In this paper is reported the way of simulation of thermohydraulic systems as whole real systems consisting of many parts. The crucial demand in our approach was to develop a software within the whole thermohydraulic system could be quickly designed and simulated under different conditions. Therefore, new graphical ”drag and drop” thermohydraulic library is being developed under MATLAB/Simulink. Pivotal point in our approach was the incorporation of results obtained in CFD simulations and the incorporation of measured data from calorimetric tunnel. Designed and simulated easy cooling circuit is shown as an example of application of developed software. The results for various composition of cooling fluid and various RPM of pump are presented.
