文摘
- •
Turbulent natural convection flow in a channel with non-uniformly heated walls is studied.
- •
Two-wall-heated staggered arrangement in both vertical and tilted flow channels is analysed.
- •
Large Eddy Simulation demonstrates that vertical flow channel has a higher chimney effect.
- •
Two-wall-heated staggered arrangement results in higher volumetric flow rate of entrained air.
