ICEM CFD is a powerful pre-processing tool used to create high-quality structured and unstructured meshes for CFD simulations. In a nozzle flow analysis, the geometry is first imported or created within ANSYS Workbench. The domain is cleaned and divided into parts like inlet, throat, and outlet for accurate meshing. ICEM allows precise control of mesh density near the nozzle walls and throat region where pressure and velocity gradients are high. The generated mesh is exported to Fluent through Workbench for flow simulation. Boundary conditions such as inlet pressure and outlet static pressure are defined. The simulation predicts velocity distribution, pressure variation, and Mach number along the nozzle. Post-processing helps visualize shock waves and expansion regions. This setup is commonly used to analyze convergent-divergent nozzles for aerospace and propulsion applications.
