Study on the Chaotic Behavior of Smoke Plumes and Fire Trends

Abstract:

The partial differential equations describing fire smoke plume is deduced from the general equation buoyant jet. Applied Lorenz model to study the chaotic behavior of smoke plumes, discussed the nature of evolution equations within the Prandtl number changes, at the same time the emergence of chaotic solutions for the numerical analysis. Smoke plumes appear chaotic, indicating that the flow state changes from the stable convection to unstable convection, at this condition may produce fire whirlwind, so that disaster to expand. Contact Fire actual process parameters when generating chaotic solution, we propose a disaster prediction and control of ideas.
