CFD Fire Simulations with Four Turbulence Models and Their Combinations

Abstract

Four turbulence models and their combinations were tested and compared in simulating compartment fires with Computational Fluid Dynamics (CFD). These four models were the algebraic model, the standard k-ε model, the low Reynolds number k-ε model and the modified forms of the k-ε model with sec ond-order corrections. Mixed Turbulence Model System (MTMS) with more than two turbulence models used in different locations was also investigated. Nine nu merical experiments were performed. It was found that results predicted were similar in using different models and their combinations.
