INTENSE-INsights into The Navier Stokes Equations

An Unsteady Navier Stokes solver using SIMPLE on a staggered grid with a blended second-first order interpolation for face-velocities

INT(E)NSE is (an intended pun and) acronym for IN-terpolated Two-D(E)-Navier-Stokes-Equations. This is an unsteady Navier-Stokes solver I developed during my free time. Interpolations for the face-velocities are done using a blended second-order and first-order accurate scheme to be able to capture the vortices. Pressure-velocity coupling is achieved using SIMPLE algorithm and the time-stepping is first order accurate following backward finite differencing discretization.
