S10 looks to be seeing a max velocity of 300m/s so I'd check convergence carefully. You also tend to see poor mass balance on a transient if there is any pulsing in the flow field: you need to monitor what goes in, what leaves and what's inside the domain for these models. nS2 & S5 look OK, but check mesh resolution around the jet. Have you enough cells to resolve the full gradients? n
