Water Spray Dynamics in Fire Flows

摘要: Lagrangian model of droplet movement in axisymmetrical fluid flow is considered application to water sprays active fire control systems, such as sprinklers, aerosols and mists. In contrast previously known models equations motion are integrated much more general form, with axial velocity being arbitrary function two spatial coordinates. Second major advantage the that it fully accounts for evaporation. Explicit formulas derived vaporization rate density drag force at any location flow. Such directly applicable a number engineering problems, example estimating compartment cooling rates by sprays, studying smoke layer destabilization sprinkler or mist sprays.
