Ceiling Fan Simulation in a Room Using Ansys Fluent | Adding Fan Boundary Condition in CFD
Ceiling Fan Simulation in a Room Using Ansys Fluent | Adding Fan Boundary Condition in CFD Introduction In this tutorial, we will perform a CFD simulation of a ceiling fan inside a room using Ansys Fluent. We will also learn how to add a fan boundary condition to simulate airflow behavior accurately. Step 1: Setting Up the Geometry in Ansys Open Ansys Workbench and create a new Fluid Flow (Fluent) Project . Use SpaceClaim or DesignModeler to create the room and fan geometry. Ensure that the fan blades are modeled properly or import the 3D fan model. Step 2: Meshing the Model Open the Meshing Tool in Ansys. Apply a fine mesh around the fan for better resolution. Use inflation layers near walls for accurate boundary layer calculations. Step 3: Defining the Boundary Conditions Open Ansys Fluent and import the mesh. Set the room walls as no-slip boundaries. Define the fan region and apply the fan boundary condition . Set the inlet velocity and outlet pressure as per simulation r...
