WebbThe parallel-in/ serial-out shift register stores data, shifts it on a clock by clock basis, and delays it by the number of stages times the clock period. In addition, parallel-in/ serial-out really means that we can load data in parallel into all stages before any shifting ever begins. This is a way to convert data from a parallel format to a ...

WebbPISO and SIMPLE are standard CFD solvers for incom-pressible ﬂows and we followed [14, 27] in their implemen-tation. We used the ﬁnite volume method (FVM) to dis-cretize Navier-Stokes equations which are then solved iter-atively until convergence.
