A Thermal Protective Clothing-Air-Skin Heat Conduction Model and Its Analytical Solution

  • 摘要: 建立了高温环境下热防护服-空气-皮肤的热传导模型.利用热传导时,层合界面间温度相等和热流量连续的条件,结合微分思想,用分离变量法推导了微小时间段内模型热传导的解析解,然后通过循环得到整个时域内的解析解.利用求得的解析解分析了在80 ℃的环境温度下模型各位置温度和热流密度的变化情况,以及在不同环境温度下皮肤表面温度变化和热损伤情况.该求解方法可用来分析一般层合结构传热问题,计算结果对热防护服的设计和效果评价具有一定的参考意义.
