The turbulence is governed by the Navier-Stokes equations, which describe the motion of a fluid. However, the Navier-Stokes equations are nonlinear and difficult to solve for turbulent flows.
The momentum transfer is governed by the conservation of momentum equation, which states that the rate of change of momentum is equal to the sum of the forces acting on the fluid element. The conservation of momentum equation is expressed as: The turbulence is governed by the Navier-Stokes equations,
The mass transfer is governed by the conservation of mass equation, which states that the rate of change of mass is equal to the sum of the mass fluxes into and out of the system. The conservation of mass equation is expressed as: The conservation of momentum equation is expressed as:
