Comparison of a Radiation Model with Experiment in a Diesel Engine 981452
A radiation model for a direct injection diesel engine was developed. Measurements of the thermal radiation with a measurement system including a radiation heat flux gauge were obtained in a diesel engine over a wide range of operating conditions. Comparisons are presented between calculations using the proposed model and experimental results, which indicate the radiant heat flux is a function of the mass burn rate, adiabatic flame temperature, soot emissivity, zone size, and etc. Furthermore, the model predicts variations of the ratio of radiation and the total heat transfer that is depending on engine load, speed and compress ratio.
