In the catalytic reaction system, the internal and external diffusion have a great impact on the total reaction rate through the influence on the mass transfer process. The internal diffusion in porous channels has been well investigated by statistical mechanics on the influence of wettability, roughness, and electric properties of channel walls. By contrast, the influence of external diffusion needs to be further studied such as, how the active motion of particles impacts the mass transfer. Herein, by using the lattice Boltzmann method coupled with mass transfer process, the influence of the forced rotation or vibration of the catalyst particle was studied. A circular particle with constant interfacial boundary concentration was considered, and the immersed moving boundary and non-equilibrium extrapolation methods were chosen to treat the liquid?particle interface. The effects of rotational speed, vibrational amplitude, and frequency on mass transfer were investigated. The simulations indicated that when only considering diffusion, particle rotation inhibited mass transfer. The higher the rotation speed, the worse the mass transfer, while the overall suppression effect was not significant. The particle streamwise vibration enhanced mass transfer significantly. The lock-on frequency was about 1.9, and the enhancement amplitude reached 10%. Increasing the amplitude and Reynolds number strengthened the mass transfer, and the lock-on frequency moved towards the low frequency direction, while the Schmidt number had little effect on the value of the lock-on frequency. The transverse vibration was also compared with the streamwise one and showed greater enhancement of Sherwood number at a lower frequency. This numerical results not only demonstrated the feasibility of the lattice Boltzmann method for simulating the forced convection mass transfer process but also provided a route for enhancing mass transfer.
