This is the crucial contribution to ∇ * (ρv); the other two contributions vanish in this example. We have a net outflow of fluid, which causes a decrease in the density of the fluid in the control volume, in accordance with equation 5.John Denker...
只要液體有足夠的密度構成一個連續體,且不包含游離分子,且運動速度遠小於光速,它就能夠以牛頓流體與Navier - Stokes方程,這類由非線性的微分方程組來描述流體所受到的外界壓力與速度。而非簡化的方程式就沒有ㄧ套通用的解法(general closed-form solution),所以這類方程式只被應用在電腦運算流體(Computational Fluid ...

the Navier-Stokes equation and thecontinuity equation, which are the basic mathematical equations of fluid dynamics (Zawawi et al., 2017;Aubry et al., 2005). Computational Fluid Dynamics (CFD) analysis is a complex process that simulates fluid flow and heat transfer in various engineering and ...
