Understanding thee drag forces acting on submarine huls is essential for optizizing their design and performance. Fluid dynamics calculations help pt predict how submarines interact with water, influencing speed, fuel effecency, and manévrability.

Basics of Drag Forces

Drag force is the resistance experienced by an object moving treamgh a fluid. For submarines, water creates this resistance, which depens on then shape, size, and speed of the hull. Te primary approents of drag include form drag, skin friction, and wave- making resistance.
