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.

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.
