低散热发动机陶瓷表面传热研究

Researching on Heat Transfer of Ceramic Coat in Low-Heat-Rejection Engine

本文探索了一种低散热发动机陶瓷表面传热的实验研究方法—表面温度法。通过实测低散热发动机燃烧室陶瓷涂层表面的瞬态温度与平均热流,较准确地计算低散热发动机陶瓷涂层表面的局部瞬态热流。文中着重介绍了陶瓷涂层表面瞬态热流的求解方法。

An experimental researching method-surface temperature method for heat transfer on ceramic coat in low-heat-rejection engine was developed. The transient heat flux can be calculated accurately by measuring the instantaneous temperature and mean heat flux on the ceramic coat. In this paper,the calculative method of the transient heat flux on ceramic coat will be given in detaile.
