Problem DescriptionAir ducts, like those found in construction and transportation industries, are typically redesigned many times before approval. Each time a new configuration emerges, computational fluid dynamics (CFD) engineers simulate the flow to determine the design's performance. The duct model used in this example is an abstract shape in which air flows through one opening and out of the other, as shown in the diagram below. Inlet Outlet Detailed view of the midsection Detailed view of an opening The inlet air velocity is 5 m/s, and the outlet pressure is 0 N/m2. This flow scenario is representative of a standard home appliance, like a clothes dryer, venting air through a duct to the air outside. To analyze the duct's performance, you will calculate the pressure drop and outlet flow velocity. You will also generate various types of plots to determine how to improve the original design. WorkflowThe workflow diagram below provides an overview of the example. The diagram shows the apps that you use as you perform the steps in sequence. Clicking a number in the diagram opens its corresponding step in the example.
You should complete the workflow steps in the order in which they are listed. Deviation from the instructions associated with each step might cause model or scenario errors, which might prevent convergence of the simulation. |
