dc.description.abstractIn this investigation, the thermal and hydraulic performance of solar air heater duct roughened with non-uniform cross-section square wave profiled transverse rib is carried out using Computational Fluid Dynamics software ANSYS Academic Research CFD 15.0. The 3-D investigation considered parameters as relative roughness pitch from 4-30, relative roughness width from 10-310, relative roughness height from 0.015-0.043 and Reynolds number from 3000-15000. The turbulence model RNG k-ε with enhanced wall treatment and one periodic length was selected for analysis. The CFD methodology has been validated with the experimental results available in literature. The maximum enhancement in Nusselt number and friction factor over smooth duct was found to be 2.22 times and 3.40 times respectively at relative roughness pitch of 10, relative roughness width of 85, relative roughness height of 0.043 and Reynolds number of 15000. The maximum thermohydraulic performance parameter was found to be 1.49 at relative roughness pitch of 10, relative roughness width from 85, relative roughness height from 0.043 and Reynolds number of 12000.en_US
