Overview
This project involved a high-fidelity computational fluid dynamics (CFD) simulation to estimate the resistance and required power of a 31-meter planing hull cruising at 17 knots. The analysis was essential for optimizing propulsion system sizing and verifying performance prior to physical trials.
Approach
Using STAR-CCM+, a two-degree-of-freedom (2DOF) simulation was conducted, allowing the hull to move in heave and dynamic pitch. This setup accurately captured the vessel’s running trim and vertical motions at the specified speed.
Validation & Standards
The CFD results were validated against experimental data and showed excellent alignment, with percentage error well within International Towing Tank Conference (ITTC) tolerance limits, ensuring reliability and credibility of the findings.
Software & Tools
- STAR-CCM+
- Overset mesh
- Volume of Fluid (VOF) for free surface modeling
Key Outcomes
✅ Accurate power prediction at 17 knots
✅ Verified compliance with ITTC standards
✅ Reliable input for propulsion and hull optimization
