Fluorescence imaging of mixing flowfields and comparisons with computational fluid dynamic simulations

Abstract

This paper compares computational and experimental fluorescence images of the mixing flows associated with a number of fuel injectors, injecting hydrogen fuel into a supersonic coflow. The favourable comparison allows us to establish the reliability of the computational fluid dynamic modelling on which the theoretical images are based. Theoretical calculations of mixing performance parameters are then used to assess the mixing characteristics and performance of the injectors. Show more
