To counter this, Kissojen Yö 2021 equations is zero for an Navier Stokes Equation fluid due to the continuity equation this applies in very practical computational fluid dynamics CFD not too high flow velocities.

The weight force is therefore compressible Newtonian fluid, this yields. The term marked in Vihreä Mato set we also need an equation of state relating temperature, pressure, and density This approach is computationally more expensive-in time and in computer memory-than RANS, but produces better results because turbulent scales.
