Summary:

Digital computer methods were used to investigate the behavior of engine operating characteristics with a time-varying gas-film heat-transfer coefficient and gradual buildup of combustion-chamber deposits. Simulated engine runs were made with a "clean" engine having different wall materials and operating at different engine speeds as a basis for comparison.From the data calculated, heat transfer rates were established and inferences drawn regarding trends of detonation, preignition, and volumetric efficiency during the deposit buildup period.It was found that, while thermal resistance (x/k)d of the deposit layer is the most important parameter, a secondary parameter of interest is the thermal penetration, , in comparing the effects of deposits of different properties
