Industrial airflows numerical simulation in ducts and devices using all-speed algorithm in structured meshes

Abstract

Transportation, separation and drying of agricultural products harvested in nature, such as sugarcane without burning and grains (soybeans and others), requires the proper operation of industrial devices, because will be present besides products such as straw, earth and boulders. These devices must be capable of separating the various component parts of the raw materials of agricultural production to storage and processing. Such separation processes are fully understood and executed with detailed knowledge of the flow fields, indicating the intensity and direction of the velocity vectors. These parameters can be obtained with the use of a numericalcomputational model of equations of non-viscous fluid mechanics. To do this, you can use the Euler equations 2-D to represent how develops the flow within ducts and industrial devices, making it possible to meet the local and global behavior in various parts, from the entrance of the agricultural product out of this. This allows you to check the need for constructive adequacy scale issues or subsidize the improvement of the process of separation of the agricultural automatically. Industrial applications include transportation, separation and drying (heat transfer), grain, sugar cane and other agricultural products.
