Development of CFD model for optimization of microchannel heat exchangers for sCO2 application

Popis výsledku v původním jazyce

Compared to conventional heat exchangers (HX), microchannel HX are characterized by compact geometry and at the same time can provide comparable thermal-hydraulic (TH) performance. Utilization of this kind of HX is suitable for design of energy circuits with supercritical CO2 as a working fluid, where small dimensions of the facility are desirable. Both computational and experimental analyses are required to optimize the HX geometry in terms of heat transfer and pressure drop. A computational CFD model able to deal with specifics of SCO2 fluid and to simulate TH behavior of various shapes of the channels has been developed at Research centre Rez (CVR). Description of the model along with the first results will be described in this paper. The results will be utilized as a support for an experimental program focused on testing of several HX mock-ups on the sCO2 loop of CVR and also for future validation of the CFD model.
