ABSTRACT

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.
