| Title of the article | The flow parameters of structure elements of a fabric filter by gas flow in CFD-model |
| Abstract. | The numerical researches of 50 micrometer in diameter obstacles model flow in channels 2•10-3 m and 2•10-4 m wide are carried out by means of the methods of computational fluid dynamics. The two-dimensional flow are considered at values of Reynolds number for an obstacle Reob equal 0,1, 10, 100. The obstacles are analogies of fibers and threads of fabric filters. The purpose of the work was to determine the main parameters of the obstacles flow depending on Reob. The flow characteristics of a single obstacle, influence of adjacent elements (channel walls, neighboring obstacles) on formation of the flow and the boundary layer around the obstacles are studied as a result of the researches. Velocity of flow and thickness of viscous layer around the obstacles are determined. The features of the obstacles flow in the range of sizes less than 10-3 m are revealed. As a result of the researches it is determined that the parameters of flow filtration in the porous medium change in the sufficiently wide range depending on its geometric characteristics. |
