11. 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

12. Optimal Pin Fin Heat Exchanger Surface
Abstract : This research presents the results of numerical study of heat transfer and pressure drop in a heat exchanger that is designed with different shape pin fins. The heat exchanger used for this research consists of a rectangular duct fitted with different shape pin fins, and is heated from the lower plate. READ MORE

13. Sustainable building ventilation solutions with heat recovery from waste heat
Abstract : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. READ MORE
