CFD Simulation of Vessel with aerofoil NACA 0012 and NACA 0015 Fin Stabilizers Using ANSYS

Conduct a Computational Fluid Dynamics (CFD) analysis to evaluate the hydrodynamic performance of a vessel equipped with fin stabilizers based on NACA 0012 and NACA 0015 airfoil profiles. Scope of Work: 1. Geometry Development: • Create detailed 3D models of the vessel’s hull and fin stabilizers using NACA 0012 and NACA 0015 airfoil profiles. • Ensure accurate scaling and positioning of fins relative to the hull. 2. Mesh Generation: • Develop a high-quality mesh for the computational domain, emphasizing finer elements near the fin surfaces to capture boundary layer effects. 3. Boundary Conditions and Setup: • Define appropriate boundary conditions, including inlet velocity, outlet pressure, and wall conditions for the hull and fins. • Specify fluid properties corresponding to operating conditions. 4. Turbulence Modeling: • Select and implement a suitable turbulence model, such as the Shear Stress Transport (SST) model, to predict flow separation and vortices around the fins. 5. Simulation Execution: • Run steady-state or transient simulations based on project requirements. • Monitor convergence criteria and ensure solution stability. 6. Results Analysis: • Analyze key performance metrics, including lift and drag forces on the fins, pressure distribution, and flow patterns. • Compare the performance of NACA 0012 and NACA 0015 fin profiles. 7. Reporting: • Compile a comprehensive report detailing the methodology, simulation setup, results, and conclusions. • Include visualizations such as contour plots and vector fields to illustrate findings. Deliverables: • 3D CAD models of the vessel and fin stabilizers. • Mesh files and ANSYS project files. • Simulation results and data files. • Final report with analysis and conclusions. Qualifications: • Proficiency in ANSYS CFD tools. • Experience with marine vessel simulations and airfoil analyses. • Strong background in fluid dynamics and turbulence modeling.
