The physical properties of working fluids—in terms the Prandtl number—play a crucial role in determining their thermal performance internal flow, especially viscosity. This study first considers thermo-hydraulic and entropy generation sinusoidal corrugated channel two configurations: symmetrical (raccoon) asymmetrical (serpentine). Results are presented for different ranges operating parameters, such as 100≤Re≤700 0.72≤Pr≤90, geometrical parameters wave amplitude-to-wavelength ratio 0.2≤α≤0.6. In addition, results channels were compared with each other's straight channel. Control transport equations solved using finite element methods. It was found that flow inside wavy generated re-circulatory reigns, size affected by well Reynolds number. Also, employing high values Pr extremely enhanced heat transfer rate (HTR) over all α both raccoon serpentine channels. indicated have higher HTR factor to Finally, dominated viscous its decrease number focused on enhancement due importance many industrial applications where dissipation is critical work, including exchangers sinks. Thus, current numerical simulation primarily suggests utilizing one, nearly same total generation.
