Shaping a Non-Uniform Inflow of Mediums to Enhance the Performance of a Double-Row Fin-And-Tube Crossflow Heat Exchanger

The article presents results of numerical and experimental analyses a tube-and-fin heat exchanger. numerous studies performed so far have proved that non-uniform inflow mediums in such exchangers may significantly affect their performance. aim the presented this is to investigate impact but controlled air on double-row exchanger was first modeled numerically determine its output at uniform mediums. same model used simulate operation air. Cases an uncontrolled as well gas were next investigated experimentally, using purpose-designed test station. By controlling inflow, it possible enhance performance, up 23.3% compared flow. show positive effect be even over 6.5% better than variant with inflow. effects water simulated numerically, also shown improvement device by 6.4% analyzed case.
