Authors Abstract
Content
The prediction procedure for the instantaneous radiative heat flux from the flame to the wall in a diesel engine combustion chamber is presented. By regarding the unsteady flame in a diesel engine as quasi-steady, the results obtained in experiments on radiative heat transfer in steady confined flames are applied. The concept of effective excess air ratio which controls the luminous flame radiation and which is strongly related to the fuel properties is introduced. The calculation is easily carried out by using pressure, heat release rate, effective excess air ratio, overall excess air ratio, and a simple model for temperature. A very good agreement is obtained between calculation and the experiment.
