The influences of particle mass loading on mean and instantaneous particle distributions in precessing jet flows

► We examine effects of mass loading on particle distribution from a precessing jet. ► We measure instantaneous planar concentrations and analyse particle clusters. ► We found for mean flows, particle mass loading may be simulated by flow momentum. ► We found that for the mean distributions, momentum transfer is not dominant. ► For particle clusters momentum transfer between phases still has an influence.
