Efficient Modeling of Turbulence–Radiation Interaction in Subsonic Hydrogen Jet Flames

Abstract

A model for simulating the radiation fields surrounding turbulent hydrogen jet flames is presented. Similar to previous studies, turbulance–radiation interaction (TRI) is modeled using a stochastic methodology. The present investigation differs from previous studies in a number of aspects. A β probability density function (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 runtime of the model to approximately one-tenth 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.
