Tạo vùng cho ổ cắm: 1. 2. Tạo một khu vực hỗn hợp 2D gọi là Outlet. Chọn mặt hình chữ nhật vững chắc với mức cao nhất X-phối hợp để áp dụng nó dẫn 10: Hệ thống sưởi ấm Coil 1. Tạo một phác thảo mới | Tutorial 8 Annulus Generate to create the solid. Select Extrude from the 3D Features Toolbar. 7. Set Base Object to be the sketch that you have just created Sketch1 and Depth to ft. 8. Click on The geometry is now complete. 1. Select File Save to save the geometry file. 2. Mesh Generation First open CFX-Mesh. 1. Switch from DesignModeler to the Project Page using the tabs at the top of the window and click on Generate CFX Mesh to open CFX-Mesh. Setting up the Regions Create the 2D Regions 1. Create a Composite 2D Region called rotwall on the inner wall which will subsequently be rotating in the CFD simulation. 2. Create a Composite 2D Region called SymP1 on the planar face with the lowest Z-coordinate. 3. Create a Composite 2D Region called SymP2 on the planar face with the highest Z-coordinate. Setting up the Mesh Set the Maximum Spacing 1. Click on Default Body Spacing in the Tree View which is contained in Mesh Spacing. 2. In the Details View change Maximum Spacing to feet and press Enter on the keyboard to set this value. If you are using geometry which has come from the Parasolid import route use the value m. This mesh will be used to simulate the flow of a non-Newtonian fluid in CFX-5 with its viscosity depending upon the shear strain see the CFX-5 example Tutorial 11 Non-Newtonian Fluid Flow in an Annulus for more details . A fine mesh is required on the inner and outer radius walls to resolve the shear layers and accurately predict the viscosity variation in the boundary layer regions. You will use inflation to create layers of prismatic elements on the Wall boundaries. For this tutorial you will use the First Layer Thickness option which allows you to set the height of the first prism layer . the one which actually touches the edge of the geometry . Successive prism layers are then added each one of thickness equal to the thickness of the previous layer multiplied by the Expansion Factor until the height of the next prism layer is .
