Interior Proliferation and its Improvement of Hydrogen Sulfide from Hot Springs Gas

Abstract

For a healthy environment for hot spring recreation, this study discussed the diffusion in the bathroom of hydrogen sulfide gas from hot sulfur springs for an improvement of this harmful situation. Based on empirical measurements and then comparing the results with CFD simulation, the analysis exposed the distribution status of indoor hydrogen sulfide and its diffusion behavior. Results indicate that sulfur springs produce high levels of hydrogen sulfide that are hazardous. And the high concentrations can be improved under ideal ventilation, which was determined by the air exchange rate, flow field efficiency, turbulence and vortex phenomena.
