Numerical investigation of the air-side performance of louver fin-and-tube radiators having rectangular, tapered and airfoil section configuration

Numerical investigation of louver edges effect on the performances of louvered fin compact heat exchanger

“…Factors were found independent of fin pitch and decreased with the increase in tube pitch. The air side performance of tapered, airfoil, and rectangular LFCHE was numerically studied, with different louver angles and lengths [ 32 ]. The highest Nusselt number and minimum friction factor were achieved with the airfoil design, particularly at a louver angle of 23 .…”
