Navier-Stokes equation. This equation was formulated by Claude-Louis Navier and George Stokes. It is used to model the movement of fluids and is applied in numerous situations such as aerodynamics research, computer modeling of fire, smoke, ocean currents, weather, blood flow and many others. T is the total stress tensor, f represents the body forces acting on the fluid, nabla (inverted triangle symbol) is an operator used in mathematics, the symbol is the partial derivative.
