摘要: Abstract It is shown that similarity solutions in strong buoyant plumes (plane or axisymmctric) exist if a local characteristic turbulent diffusion coefficient varies inversely proportional to the square of gas density plume. The formulation implies proper dependent variable for temperature (density) defect ΔT/0(Δρ/ρ), where ΔT( Δρ) from ambient (density), T0(ρ0), and ρ same applicable further downstream source when plume becomes weak. form variable, ΔT/T0, proposed both weak different ΔT/T( Δρ/ρ0), previously used plumes. Long experience with fires recent experimental results variations along axis support use ΔT/T0. solution consistent Morton's (1965) model f...
