Calculations and measurements are presented of the velocity and “fuel” concentration fields in a motored axisymmetric engine where the fuel spray was simulated by a transient gaseous (Freon-12) jet injected into the disk chamber through a single-hole nozzle mounted on the centrally located inlet/exhaust valve. Freon concentration was measured by laser Rayleigh scattering and predicted by a multi-dimensional method. The measured jet was found to spread appreciably faster than the predicted one, for reasons which are not well understood.
