Abstrakt: The chemical compound Carbon Dioxide (CO2) is currently utilized as a naturalistic cooling fluid for a variety of cooling techniques. The aim here is to investigate the heat transfer (HT) and inflow proprieties of supercritical carbon dioxide (SC-CO2) empirically throughout a confined flow extruded copper model with a regular configuration of 17 fins and 16 aqueducts, a rectangular shape with a hydraulic diameter of 1.5 mm. In this work, chilled copper blocks were affixed to one and the other side of the model to keep them within the desired temperature. Also, 10K-type thermometers were used to detect topical heat fluxes (HFs) and heat levels at the test section's outer layer. Novel correlations methods for inflows were proposed in order to forecast the friction factors of supercritical pressure carbon dioxide (SC-CO2) in confined flows. Throughout the research, the impact of the inlet liquid temperature, pressure, HF, and inflow path on the heat load heat transfer (HT) in confined flows was investigated by measuring local HT factors, liquid mass heat, and wall temperatures. The results show that in the close-crucial zone, increased HT rates were reached. Besides that, the model pressure, bulk velocity, and carbon dioxide heat are all found to have a substantial influence on HT. [ABSTRACT FROM AUTHOR]
