Numerical Simulation Of Vaporous Hydrogen Peroxide Diffusion Under Different Speed

This paper adopts the computation fluid dynamics(CFD) to research the diffusion law of vaporous hydrogen peroxide(VHP) under different inlet velocities include 0.1m/s, 0.2m/s and 0.4m/s. The results show that when the inlet velocity is 0.4m/s, the concentrations of VHP in different locations can meet the decontamination demand but the consumption of hydrogen peroxide solution is large. When the inlet velocity is 0.1m/s, at 1200 seconds the lowest concentration is only 6ppm, which cannot meet the demand of the decontamination. When the inlet velocity is 0.2m/s, the vaporous hydrogen peroxide is evenly distributed in space and the concentrations can meet the decontamination demand, and the hydrogen peroxide solution also consumes less.
