the science of LZR'ing

Skin drag is inherent to the material properties over which a fluid flows and to the local flow conditions (speed in particular) as it is induced by the local velocity gradients (on your body, the water velocity is 0 m/s; away it is faster; the gradient creates a shear due to the viscous property of the fluid)." Form drag is due to the presence of one's body travelling through the fluid, and what is desirable is to make the flow path as smooth and undisturbed as possible. Dr. Morvan said, "With CFD analysis we were able to use the compressive properties of the suit to make the swimmer as hydrodynamically efficient as possible; some simulation were also used to help train/educate swimmer in fact, highlighting the effects of one's cap or finger positions on one's performance."
