Plume expressions proposed in the literature are assessed using fire field models or application of Computational Fluid Dynamics (CFD). Among the field models, the two-equation k-ε turbulence model is widely used for its robustness and simplicity. Tuning the parameters concerned would give better results. In this article, the diffusion coefficient and Prandt numbers are tuned. Numerical results are compared with experimental data reported in the literature. It is confirmed that the plume expressions are good enough for use as design equations.
