Second, we will apply the principle of conservation of momentum to the control volume. This is slightly more abstract and complex compared to the previous case but eventually, this reduces to the incompressible Navier-Stokes equations. ∂u∂t+u∂u∂x+v∂u∂y=−1ρ∂p∂x+ν(...
Theprojection methodis an effective means ofnumericallysolving time-dependentincompressible fluid-flowproblems. It was originally introduced byAlexandre Chorinin 1967 as an efficient means of solving the incompressibleNavier-Stokes equations. The key advantage of the projection method is that the computations...
