摘要
Effects of nanofluid flow and protrusion transverse rib roughness particle concentration, particle diameter, stream wise pitch, span wise pitch, relative print diameter ratio, and Reynolds number on the thermal and hydrodynamic performance of square channel were analyzed. The nanofluid was prepared as solid nanoparticles of Al2O3 suspended in distilled water. Thermal hydrodynamic performance was determined for different sets of protrusion transverse rib roughness and flow parameters. The highest value of thermal hydrodynamic is observed at nanoparticle concentration of 4.0%, particle diameter of 30, stream wise pitch, of 1.79, span wise pitch of 1.79, and relative print diameter ratio of 1.0. The maximum value of the hydrodynamic and thermal performance was 2.37 for the range of parameters examined.
