Understanding the Role of Turbulence Models and Mesh Resolution in Fire Dynamics Simulation
Introduction
Fire engineering involves the study of fire behavior, fire suppression, and fire protection systems. In this summary, we explore the intertwined roles of turbulence models and mesh resolution in fire dynamics simulations, focusing on their significance, utilization, and impact on Computational Fluid Dynamics (CFD) simulations in fire engineering applications. Fluid dynamics simulation plays a crucial role in various engineering applications, ranging from aerodynamics in aerospace to fluid flow in industrial processes. One key aspect of fluid dynamics simulation is the modeling of turbulence, which significantly impacts the accuracy and reliability of the simulation results. In this summary, we delve into the importance of turbulence models in Computational Fluid Dynamics (CFD) simulations and explore how this knowledge can be effectively utilized.
Turbulence Modeling in CFD
Turbulence significantly influences fire dynamics, affecting flame spread, heat transfer, and smoke movement within a fire environment. Turbulence models in fire dynamics simulations aim to capture these complex interactions between fire, airflow, and combustion products within a computational domain. Accurate representation of turbulence is crucial for predicting fire behavior and assessing fire protection measures. Turbulence refers to chaotic and irregular fluid motion that occurs at high Reynolds numbers [1]. Directly resolving all turbulence scales in a simulation is often computationally infeasible, necessitating the use of turbulence models. These models aim to capture the effects of turbulence on the flow field by providing closure to the governing equations, typically through additional transport equations for turbulent quantities such as turbulence kinetic energy and turbulent dissipation rate.
