Heat transfer is a critical factor affecting the performance of metal hydrogen storage tanks. Many studies have proposed inner tubular heat exchangers for increasing the heat transfer rate between the metal powders and the exterior environment of the tanks. However, connecting cooling and...

In the present work, convection heat transfer of water at supercritical pressure in a narrow annulus at low Reynolds numbers (less than 1500) has been investigated numerically. The continuity, momentum and energy equations have been solved simultaneously using computational fluid dynamics...

A numerical three-dimensional non-isothermal hydrodynamic and thermal modeling based on the unidirectional flow analysis of stratified flow in the circular cross section pipe is developed and tested by experimental data. The model could solve the steady axial momentum equation and heat transfer...
