WebbABSTRACT Transient characteristics of plume flows generated by 0.57 m-2.0 m diameter aviation fuel pool fires in a 5.4 m wide x 2.4 m high x 130 m long tunnel for ventilation … WebbA method for in-situ optical measurements of solid and hybrid propellant rocket plumes is developed, and results from proof of concept tests are presented. The developed method inserts fiber-optic cables acting as radiation conduits into the solid-fuel combustion port, allowing optical signals to be transmitted from the flame zone to externally-mounted …

WebbThe engineering approaches used to assess plume impingement consist of two steps. The first step is to estimate the flow parameters such as density, velocity, and dynamic pressure for the plume flow field undisturbed by the impingement target. The required math models are based upon the semi-empirical source flow assumption. Webb28 nov. 2016 · On this basis, a three-dimensional numerical analysis of the effects of different chemical reaction mechanisms on LOX/kerosene engine exhaust plume flow field characteristics was carried out. It is found that multistep chemical reaction can accurately describe the combustion process in the LOX/kerosene engine, the average chamber … mildew resistant paint exterior

In hydrodynamics, a plume or a column is a vertical body of one fluid moving through another. Several effects control the motion of the fluid, including momentum (inertia), diffusion and buoyancy (density differences). Pure jets and pure plumes define flows that are driven entirely by momentum and buoyancy effects, respectively. Flows between these two limits are usually described as f… Webb3 juli 2014 · A computation fluid dynamics–simultaneous reaction model (CFD–SRM) coupled model has been proposed to describe the desulfurization behavior in a gas-stirred ladle. For the desulfurization thermodynamics, different models were investigated to determine sulfide capacity and oxygen activity. For the desulfurization kinetic, the effect … WebbThermal history modeling results show that an abnormal high paleo-heat flow of 90-110 mW/m(2) was caused by the Emeishan mantle plume activity. Based on the present-day … mildew resistant paint for basement
