L(247) GROUP 1. Run title and other preliminaries TEXT(Area Restriction With Inlet Swirl TITLE This run studies the same flow as the previous one except that incoming fluid has a non-zero u-velocity, i.e.the incoming fluid is swirling about the axis. Since NX=1, u is solved as a scalar variable; it has no pressure gradient source term. However, u influences the hydrodynamic variables v, w and p through the centrifugal force exerted on v.
