Abstract: Off-site strip rectangular fin arrays are commonly used, for example, in the marine engineering: wind and wave loading, sloshing, propulsion, mechanical engineering: pumps, fans, heat exchangers, chemical and petrochemical engs. Process: static mixing, separation, reactions, electrical eng.: equipment cooling and environmental eng.: pollutant and effluent control, fire management, shore protection, fans, heat exchangers. In designing any kind of heat sink or heat exchanger, the need to save energy and reduce costs always sets the following requirements for the design: the total heat transfer rate should be high while the volume and weight of the system should be low.
The aim of this study is to investigate experimentally the fin heat transfer performance of an offset-strip fins [OSF] at vertical and horizontal positions in the water fluid flow as cooling system. This is done at different water volumetric flow rates (Qv) from 0.5 to 2.0 L/s at constant hydraulic diameter (Dh, 0.42 m). In the present study, experiments are conducted at the range of water system temperature from 26 to 30 oC. The computations are conducted by assuming that the flow in the offset-strip fin channels is steady and turbulent at the range of Reynolds numbers from 4300 to 6000. Can be deduced from this research work, that horizontal OFS position has a high fin thermal performance than other.
