Penurunan Persamaan Navier Stokes dalam Bentuk Persamaan Diferensial untuk Gerak Fluida Laminer

Abstract

Generally set of Navier-Stokes equations describing the motion of a fluid such as liquids and gases. This equation states that the change in momentum of fluid particles depends on the strength of internal and external pressure viscous forces acting on the fluid. Therefore, the Navier-Stokes equations describe the balance of forces acting on fluid. The forces acting on the fluid style of the object (body strength) and surface forces (surface forces). To solve the Navier Stokes decline, then solved by the Analytic or theory, with substituted for the normal stress and shear stress on the forces acting on the fluid element will be obtained by balancing the forces acting on the fluid element, and then substituted into the continuity equation and kinematic viscosity for gain momentum conservation equation, known as the Navier Stokes equations. The equation is applicable for fluid with a viscosity is not equal to zero.
