Abstract: In order to improve the design and provide initial conditions for numerical simulation of spray combustion process, it is absolutely necessary to carry on cold-flow experiments for LRE injectors.These experiments, in general, include determination of distributions of flux-rate, mixture-ratio, liquid droplet size and their velocities. It has been shown that the measuring accuracy and the level of experimental automatization have been improved by the application of microcomputer in the mesurement and control system.This has laid a good example for large-scale cold-flow investigation of various injectors in future.
