热防护服-空气-皮肤热传导模型及其解析解
摘要
A thermal protective clothing-air-skin heat conduction model in high temperature environment was established. The analytical solution of heat conduction in a small time period was derived by means of the method of separation of variables under the conditions of equal temperature and continuous heat flux at the laminate interface during heat conduction, and then the analytical solution in the whole time domain was obtained through iteration. The variations of temperature and heat flux in different positions in the model at an ambient temperature of 80 ℃ were analyzed with the analytical solution. Then the surface temperature and thermal damage of skin at different ambient temperatures were calculated. The solution method applies to heat transfer problems of general laminate structures. The calculation results are of referential significance for the design and effect evaluation of thermal protective clothing.
