発電プラントにおける高温流体の漏洩を想定した皮膚内の熱伝導解析評価

When a leakage of high temperature fluid occurs in a power plant due to deterioration or damage of piping, thermal effects on the human body can be expected due to splashing of the fluid. In this study, we modeled human skin as three layers (epidermis, dermis and subcutaneous fat) and attempted to evaluate heat conduction in the skin when exposed to high temperature fluid. It was found that the temperature of the subcutaneous fat gradually increased depending on the exposure time when the fluid was at a high temperature of 100°C or higher. The severity of the burn index calculated by the temperature distribution in the area in question increased rapidly soon after the skin was exposed to the high temperature fluid, and was determined to be the most serious “Third degree heat injury” in this analysis. In the future, we will evaluate the PBI (Prognostic Burn Index) using the obtained burn index and attempt to quantify the survival rate at the time of burn injury.
