The control volume approach in fluid mechanics relies upon the conservation of energy, momentum and angular momentum. However, open channel flows are typically related to only conservation of energy and momentum. Thus, for flows of non-uniform velocity and non-hydrostatic pressure distributions, the ...
velocity, and elevation, and is valid in regions of steady, incompressible flow where net frictional forces are negligible ( as shown in the Figure below). Despite its simplicity, it has proven to be a very powerful tool in fluid mechanics. The Bernoulli equation is an approximate equation tha...
after spending days in unterstanding the source code and the mathematics of the oodles solver to add a velocity dependend source term to the navier stokes equation I now have a idea but I am not really sure if this is right. So hopefully somebody could verfify my idea and here it comes...

On the basis of the angular momentum equation for a fluid shell on a rotating planet, we analyze the intrinsic drift of a monopolar vortex in the shell. Central is the development of a general angular momentum equation for Eulerian fluid mechanics based on coordinate-free, general tensorial repr...

Equation for Angular Momentum As mentioned in the previous section, all symmetrical objects rotating about a fixed axis have angular momentum. It is expressed as L=Iω, where, L is the angular momentum in kg m²/s; I is the moment of inertia in kg m²; and ω is the angular veloc...
