基于概率分析的污垢模型初始污垢热阻的确定

Calculating Initial Fouling of Fouling Model Based on Probabilistic Approach

基于污垢形成的随机性 ,在不同风险水平的条件下 ,利用概率方法和在污垢形成过程中 ,污垢热阻达到临界可接受水平的时间遵循分布规律 ,及污垢模型本身的性质来确定线性、幂律、降率和渐近四种污垢模型的初始污垢热阻。

Based on a stochastic characteristics of fouling process and especial nature of the models,initial fouling resistance of linear?power law?falling rate?asymptotic fouling model is determined.The time to reach a critical level of fouling that is normal distribution.And some experiments are conducted,the result of the experiments agrees with the result of the predictive model.
