The effect of blade slots on flow behaviour in a fan impeller [PDF]
The use of blade slots is one of the passive methods of controlling flow in a fan impeller. Numerical CFD analyses indicate a possibility of controlling the point of flow separation in the inter-blade space depending on various configurations of the ...

Porous fixed-bed photoreactor for boosting C–C coupling in photocatalytic CO2 reduction
Solar-driven CO2 conversion to chemical fuels in an aqueous solution is restricted not only by photocatalysts but also by mass transfer. Here, a regulatable three-phase interface on a porous fixed-bed is constructed for efficient C–C coupling in ...
