Sail & Airfoil Flow Simulator

Simulate sailboat airfoil aerodynamics with real-time flow analysis.

This app uses a vortex panel method to model 2D potential flow around thin airfoils — ideal for analyzing mainsail and jib performance. Great for sailors, designers, engineers, or students.

Features:

• Interactive sail and airfoil shaping

• Real-time lift coefficient and circulation output

• Adjustable angle of attack and camber

• Visual streamline flow and panel pressure plots

• Compare individual and combined sail behavior

• Lightweight and offline — no data tracking

Use it for:

• Sail tuning and optimization

• Learning airfoil theory and flow interaction

• Understanding lift generation on rigged sails

Whether you're a sailboat racer, fluid mechanics student, or curious engineer, Airfoil Analysis helps you explore aerodynamic forces with clarity and precision.
