Abstract

This study develops a methane photocatalytic removal system using the lattice Boltzmann method (LBM), analyzing the velocity, temperature, and concentration fields in catalyst arrays of cylindrical and elliptical posts with random, ordered, and staggered distributions. The results indicated that ordered posts exhibited symmetrical flow with higher central temperatures and an outward-convex CH4 concentration gradient. The staggered posts produced sinusoidal flow patterns, resulting in inward-concave CH4 contours. For cylindrical posts, random distribution showed higher flow velocities in wider gaps and stagnation in denser regions. The elliptical posts exhibited higher flow velocity at the long axis tips and lower velocity at the short axis, causing greater curvature in CH4 concentration contours. For cylindrical posts, photocatalytic efficiency reached 56.25 % at Db = 0.2 mm. The CO2 reduction rate was 7.7 × 10−7 g/s at Fr = 40 %. The saving to investment ratio peaked at 2.15 at Od = 1.0 mm. The effect of To on system performance was minimal. At Qin = 2000 ml/min, SIR increased to 3.93. These trends were consistent across both cylindrical and elliptical posts. This study enhanced the understanding of flow and concentration distribution in photocatalytic reactions, offering valuable insights for optimizing methane removal systems.
