An Experimental and Analytical Study of the Unsteady Heat Transfer Processes in Low-Heat-Rejection Engine Combustion Chambers: REU Supplement

与传统的冷却发动机相比，低热量燃烧发动机显示出更高的效率。为了在更坚实的基础上证明效率的潜在改进，将进行实验，测量单缸柴油发动机燃烧室中几个位置的瞬时表面温度和热流。这些结果将对发动机部件与其周围环境之间的界面处的传热系数产生现实的估计。此外，这些结果将用于评估和进一步开发缸内传热过程的分析模型。

Low-heat-rejection combustion engines show promise of higher efficiencies than their conventionally cooled counterparts. To place the potential improvements in efficiency on firmer ground, experiments will be performed to measure the instantaneous surface temperatures and heat fluxes at several locations in the combustion chamber of a single-cylinder diesel engine. These results will yield realistic estimates of the heat transfer coefficients at the interfaces between engine components and their surroundings. Further, the results will be used to assess and further develop analytical models of the in-cylinder heat transfer processes.
