Abstract

A novel fixed bed photocatalytic reactor with tilted photocatalyst-coated deflectors was designed and a numerical simulation for evaluation of its photocatalytic performance by ANSYS FLUENT 15.0 was developed. The results showed that the convective mass transfer was effective near the deflectors. The air flow velocities were pretty fast with a maximum value of 0.55m/s and had larger longitudinal velocity which could enhance laminar mass transfer, near the front face where the reaction took place. While behind the deflector, the air flow even keep still and the pressure loss was 0.18 Pa. Optimized construction of the photocatalytic reactor was designed and simulated for effects verification. The results showed that the velocity distributed uniformly near the inlet and outlet and the total pressure loss decreased to 0.09Pa.
