We apply a turbulence-regulated model of star formation to calculate the starformation rate (SFR) of dense star-forming clouds in simulations of jet-ISMinteractions. The method isolates individual clumps and accounts for the impactof virial parameter and Mach number of the clumps on the star formationactivity. This improves upon other estimates of the SFR in simulations ofjet--ISM interactions, which are often solely based on local gas density,neglecting the impact of turbulence. We apply this framework to the results ofa suite of jet-ISM interaction simulations to study how the jet regulates theSFR both globally and on the scale of individual star-forming clouds. We findthat the jet strongly affects the multi-phase ISM in the galaxy, inducingturbulence and increasing the velocity dispersion within the clouds. Thiscauses a global reduction in the SFR compared to a simulation without a jet.The shocks driven into clouds by the jet also compress the gas to higherdensities, resulting in local enhancements of the SFR. However, the velocitydispersion in such clouds is also comparably high, which results in a lower SFRthan would be observed in galaxies with similar gas mass surface densities andwithout powerful radio jets. We thus show that both local negative and positivejet feedback can occur in a single system during a single jet event, and thatthe star-formation rate in the ISM varies in a complicated manner that dependson the strength of the jet-ISM coupling and the jet break-out time-scale.
