Predictive heat transfer equations have been developed to estimate the local supplementary heating necessary to support a resting diver. These formulations consider the diver's passive thermal protection in the form of a diving dress and the effects of his ambient environment upon the dress thermal resistance. The mathematical model performs a numerical analysis on discrete regions comprised of the skin, dry protective suit, breathing gas mixture and the surrounding fluid environment. The parametric properties associated with the heat transfer correlations were obtained from validated experimental heat flux and skin temperature data collected under specific environmental conditions. The supplementary heating required to maintain a diver is obtained by determining the heat flux that would be lost were he not heated and subtracting from this the normal heat flux expected from a resting euthermic subject. Applying this principle to each of the regions, it is possible to predict the supplementary heating necessary to compensate for an excessive flux.
已经开发出预测传热方程来估计维持静息潜水员所需的局部补充加热量。这些公式考虑了潜水服形式的潜水员被动热保护以及其周围环境对潜水服热阻的影响。该数学模型对由皮肤、干式防护服、呼吸气体混合物和周围流体环境组成的离散区域进行数值分析。与传热关联相关的参数特性是从在特定环境条件下收集的经过验证的实验热通量和皮肤温度数据中获得的。通过确定如果不加热潜水员将会损失的热通量，并从该热通量中减去静息恒温受试者预期的正常热通量，来获得维持潜水员所需的补充加热量。将这一原理应用于每个区域，就可以预测补偿过量热通量所需的补充加热量。
