Chorin's projection

Webof Chorin’s fully discrete projection method applied to (1.1) and proved its convergence within an arbitrarily xed time interval to a Leray-Hopf weak solution (up to a sub-sequence) by means of a new compactness argument (the standard Aubin-Lions-Simon approach fails). It seems that Chorin’s fully discrete projection method is no longer WebAs in the original projection method developed by Chorin, we first solve diffusion-convection equations to predict intermediate velocities which are then projected onto the …
