(2) the presence of the vortex flow around the flow passage between the baffle was repeatedly turned to the arc-shaped, so that the flow field distribution is highly beneficial in enhancing gas-solid separation.
(1) can be seen from the pressure field showing positive pressure at the inlet area, relatively large bezel whirlpool area, bound to baffle its existence after the formation of negative pressure zone, formed around the pressure plate, bringing filter pressure loss. And the filter pressure loss is increased with the rate of increase of imports.
Gas flow field calculated using the improved method based on SIMPLE algorithm SIMPLEC [4], the method has to improve and speed up the convergence performance. Regional integration using staggered grid mesh, the discrete convection using QUICK scheme [5]. Since the Euler field, whether fluid or particle equations equation,ed hardy paris, have the same form, the difference is the source term. Which can solve the original single-phase flow numerical method is extended to multiphase flow.

Abstract: In this paper, turbulence and particle maturation model, which is based on Euler system under the k-ε two-equation model and the particle phase as a continuum, part of the consideration of particle motion relative to the impact of no-slip fluid model, according to the conditions of use of such blinds set parameter values,http://www.mbtcipoarak.com, simulate the airflow through it when the dust filter characteristics. Calculated V-blinds in gas-solid flow filter, which reveals its internal gas pressure field distribution and particle concentration field of the basic characteristics and simulation results and the preliminary results of the comparison and error analysis, which a compelling case that the use of CFD technology in engineering design prior to the implementation or production (transformation) before the projection of the actual results and performance of feasibility. This paper by the Chinese Alliance WWW.LWLM.COM collected.

No-slip model based on basic assumptions, the particle phase momentum equation and energy equation do not exist, just given the conservation of mass or continuity equation or diffusion equation:

Figure 2, Figure 3, Figure 4, Figure 5 are the filter face velocity V = 1m / s, V = 2m / s, V = 3m / s, V = 4m / s when the gas pressure field simulation results .
So far, in engineering applications, the gas flow field model is still viable and mature is the gas as a continuum based on Euler system under the k-ε two-equation model [2]. Computational model of particle number, this paper is based on the Euler line under, the particle phase as a continuum, part of the consideration of particle motion relative to the impact of no-slip flow model [3]. The advantages of no-slip model is simple, you can use a more sophisticated treatment of the numerical solution of single-phase fluid to handle two-phase flow, the drawback is not considered relative to the fluid particle velocity and temperature slip (lag). However, in this study, only consider the case of the fluid at room temperature, particle movement, no need to consider the temperature changes, so you can use no-slip model.

Blinds dust filter is a kind of inertia. It is equipped with a lot of dust on the air channel formed by the tilt of the leaf plate block gray grid (cross-section shown in Figure 1), gray dust blocking air flow through the gate when the gap between the plates by the number of leaves into multiple airstreams , air flow through the leaf plates per share will suddenly change direction, this time, dust particles under the effect of inertia in trying to maintain the original flow direction, dust particles passing the gate blocking the entrance and directly hit the gap behind the leaf board surface,abercrombie pas cher, and around the block along the gray gate in the opposite direction of air flow direction of the pop-up [1]. This research is based on the conditions of use of such blinds set parameter values, simulate the airflow through it when the dust filter characteristics.
Authors simulate the numerical simulation of particle size selected for the 50 μm, 15 μm of the experimental standard talc, its density 2750Kg / m 3.
