WALL SURFACE DECOMPOSITION MODEL AND IDENTIFICATION OF MODEL PARAMETERS

Numerical prediction of hydrogen peroxide distributions and modeling for decontamination in indoors　Part 1

Abstract

Effective decontamination is essential and critical if indoor spaces are contaminated by various kinds of biological contaminants especially in hospital and health care facilities. Dissemination of vapor hydrogen peroxide is one of the effective ways to decontaminate biological contaminants in indoors. This study used computational fluid dynamics (CFD) method as a prediction tool for non-uniform distribution of vapor hydrogen peroxide in indoors and also the deposition/decomposition on wall surfaces. Here, CFD model incorporating reactive transport of vapor hydrogen peroxide was developed and sensitivity analyses were carried out to estimate surface concentration of vaporized hydrogen peroxide and decontamination efficiency.
