Abstract
The availability of large digital computers, the recent development of adequate techniques of numerical analysis, and the growth of knowledge about the laws of turbulence, have combined to make possible the development of a comprehensive prediction procedure for the fluid-dynamic, heat transfer and combustion phenomena which take place in diesel engine combustion chambers. The difficulties, and means of surmounting them, are discussed in the lecture; it is argued that a very useful first stage would be a procedure applicable to axisymmetrical chambers; this could be constructed by extending already established techniques and knowledge. The procedure would be of the finite difference variety, and would employ a grid which expanded and contracted to accord with the piston motion.
