N2 - We study the flow in a model Francis-99 draft tube for partial load conditions usingLarge-eddy simulation. The swirl is produced by the runner rotating with a constant angularvelocity. Within the validation step, we compare results of eddy-resolving simulations with ourParticle image velocimetry (PIV) and pressure measurements for three flow cases with differentincoming flow rates. The time-averaged velocity fields agree well in experiments and simulation.To study the dynamical features, we analyze spectral characteristics of the flow featuring a strongcoherent component. This vortical structure corresponds to the precessing vortex core (PVC)changing the shape and amplitude with the increase in the bulk velocity.
