3. Thermal and Hydraulic Performance of Enhanced Rectangular Tubes for Compact Heat Exchangers
Abstract : The thermal and hydraulic performance of rib-roughened, dimpled and offset strip fin tubes has been investigated experimentally. Results from measurements on commercially manufactured tubes have shown that rib-roughened tubes have best potential for heat transfer enhancement with moderate pressure drop increase. READ MORE
