The viscous dissipation effect on the thermodynamic performance of the curved square microchannels in laminar flow is numerically investigated. The classical Navier–Stokes equations are adopted; aniline and ethylene glycol are selected as the working fluids. The results show that the heat...

The entropy generation in Lead–Bismuth Eutectic (LBE) turbulent flow in a cooled straight tube with a diameter of 10 mm and a length of 1 m is numerically investigated taking into account the temperature-dependent of LBE properties. The standard k-epsilon turbulence model combined with...
