Comparative study of solar air heater (SAH) roughened with transverse ribs of NACA 0020 in forward and reverse direction

Comparative study of solar air heater (SAH) roughened with transverse ribs of NACA 0020 in forward and reverse direction

Experimental and Numerical investigation of heat transfer and fluid flow characteristics is carried out for SAH duct (aspect ratio, W/H = 10:1) with transverse ribs of different cross-sections (square, semi-circular and symmetric half NACA 0020 in both forward and reverse orientations) on one of its...
