A review of flow and heat transfer characteristics

The performance of heat exchangers can be improved to perform a certain heat-transfer duty by heat transfer enhancement techniques.In general,these techniques can be divided into two groups active and passive techniques.The active techniques require external forces,e.g.electric field,acoustic or surface vibration,etc.The passive techniques require fluid additives or special surface (PDF) Numerical Investigation of Heat Transfer Performance The spirally coiled tubes are fabricated by bending a 8.50 mm inner diameter straight steel tube into a spiral-coil with two different curvature ratios of 0.035,0.060.The predicted results are
