Search for Universal Minimum Drag Resistance Underwater Vehicle Hull Using CFD

Overview

A systematic CFD-based search for the universal minimum drag resistance hull form for underwater vehicles. This work evaluates a comprehensive design space of hull geometries using OpenFOAM simulations to identify fundamental limits on drag reduction.

Approach

• Parameterized hull geometry space covering major UUV form factors
• High-fidelity OpenFOAM RANS simulations for each candidate
• Analysis of drag components (pressure drag, friction drag) across the design space
• Identification of optimal hull aspect ratios and nose/tail geometries
