We prove global existence of weak solutions to two systems of equations which extend the dynamics of the Navier-Stokes equations for incompressible viscous flow with no-slip boundary condition. The systems of equations we consider arise as formal limits of time discrete pressure-Poisson schemes introduced by Johnston \& Liu {[}J. Comput. Phys. 199, 221-259, 20041 and by Shirokoff \& Rosales {[}J. Comput. Phys. 230, 8619-8646, 20111 when the initial data does not satisfy the required compatibility condition. Unlike the results of Iyer et al. {[}J. Math. Phys. 53, 115605, 20121, our approach proves existence of weak solutions in domains with less than regularity. Our approach also addresses uniqueness in 2D and higher regularity.
