20.500.12556/DKUM-67602 Modeliranje in dinamična simulacija toplotnega prenosnika Modeling and dynamic simulation of heat exchanger V diplomskem delu predstavljamo modeliranje dvojno-cevnega prenosnika toplote s sotočnim režimom. Razvili smo enostaven model prenosnika toplote in kaskadni model prenosnika toplote ter analizirali njuno dinamično obnašanje. Matematična modela smo implementirali v programu MATLAB/Simulink. Za namen primerjave obeh modelov smo izvedli niz numeričnih simulacij, s katerimi smo ugotavljali, kako se merjeni parametri (iztočne temperature) odzovejo na stopničaste spremembe vhodnih parametrov. Rezultati kažejo, da kaskadni model toplotnega prenosnika realneje opiše odzive merjenih parametrov glede na uvedbo motenj v sistem. Ugotavljamo, da bi z uporabo enostavnih modelov toplotnih prenosnikov lahko obogatili eksperimentalno delo med študijem kemijske tehnike. The thesis deals with the modeling of double-pipe heat exchanger, in parallel flow arrangement, using programme MATLAB/Simulink. We developed an ideal model of a heat exhanger as well as a more realistic cascade model and observed their dynamic behaviour. Several numerical simulations were done to compare how observed parameters (outlet temperatures of cold fluid) are responding to step changes of inlet conditions. Results indicate that cascade model of heat exchanger provides a generalized realistic response to given step changes. We conclude that the usage of general models can greatly enhance experimental work during Chemical Engineering courses. dvojno-cevni prenosnik toplote modeliranje dinamična simulacija Simulink dinamika procesov double-pipe heat exchanger modeling dynamic simulation Simulink process dynamics true true false [N.
