Abstract
A model for simulating the radiation fields surrounding turbulent hydrogen jet flames is presented. Similar to previous studies TRI is modelled using a stochastic methodology. The present investigation differs from previous studies in a number of aspects. A beta PDF is used to generate the cumulative probability density function rather than a clipped Gaussian PDF. A number of efficient numerical algorithms are implemented to reduce the run-time of the model to approximately 1/10th of the time required using accepted numerical methods widely promoted in the literature. This has enabled the model including TRI to be validated using measured heat fluxes.
