Sažetak:
In this paper an analysis of heat transfer and fluid flow of compact heat exchanger has been done. 3D numerical simulation results of a heat exchanger with microchannel coil were compared with experimental results carried out in this research. Microchannel coil composed of flat tubes with rectangular microchannels of different geometries has been installed in an open circuit wind tunnel. Air and distilled water were used as working fluids in heat exchanger with single phase heat transfer. Same geometry and parameter setup have been analyzed with commercial fluid flow and a heat transfer solver Fluent. Air/water model has been used. Good agreement between experimentally measured and calculated results has been accomplished. The influence of different microchannel geometry on heat transfer effectiveness and pressure drop have been studied numerically. Comparison of results has been made accompanied by the commentaries and final conclusions.
