Abstract: The present work provides a reliable computational framework to investigate the laminar and turbulent forced convection of sodium and sodium–potassium (Na, NaK) in small-scale heat sinks with hydraulic diameters between 1 ...

Abstract: Analytical and computational fluid dynamics (CFD) analyses confirmed the presence of apparent slip for water flow in microchannels with equivalent hydraulic diameter, Dh < 103μm, markedly decreasing the friction number, ...

Abstract: An analytical expression for turbulent kinematic viscosity (νt), based solely on the hydraulic Reynolds number (Re), was derived and evaluated. The analytical expression is valid for the fast estimation of νt for internal, ...

Abstract: This investigation is devoted to evaluating the thermal hydraulics behavior of sodium-based (Na) miniature heat sinks. The investigated geometrical parameters cover a range of 0.143–1 for heat sink aspect ratios, 0.267–21.7 mm ...
