Large chamber experiment for measuring vhp distribution and corresponding CFD analysis: Numerical prediction of hydrogen peroxide distributions and modeling for decontamination in Indoors - Part 2

To keep healthy and sanitary indoor air quality level, the development of effective decontamination measure in indoor environment will be important issue because the indoor environment generally can be contaminated with various contaminants. Here, we focused on hydrogen peroxide (H2O2) and discussed its application to decontamination in indoors. This study used computational fluid dynamics (CFD) technique as a prediction tool for non-uniform distribution of vapor hydrogen peroxide in indoors and also the decomposition on wall surfaces. In this Part 2, concentration distributions of vapor hydrogen peroxide in large scale climate chamber were precisely measured and CFD analyses with the same scenarios of the experiment were carried out to validate prediction accuracy and decontamination efficiency.
