@article{DomnguezVzquez2022ClosedSP, title={Closed Sparse—A Predictive Particle Cloud Tracer}, author={Daniel Dom{\'i}nguez-V{\'a}zquez and B. F. Klose and Gustaaf B. Jacobs}, journal={SSRN Electronic Journal}, year={2022} }

A closed and predictive particle cloud tracer method is presented. The tracer builds upon the Subgrid Particle-Averaged Reynolds Stress Equivalent (SPARSE) formulation first introduced in [Davis et al., Proceedings of the Royal Society A, 473(2199), 2017] for the tracing of particle clouds. It was later extended to a Cloud-In-Cell (CIC) formulation in [Taverniers et al., Journal of Computational Physics, 390, 2019] using a Gaussian distribution of a cloud’s influence over a meshbased, velocity…

A Lagrangian particle cloud model is proposed that accounts for the effects of Reynolds-averaged particle and turbulent stresses and the averaged carrier-phase velocity of the subparticle cloud scale on the averaged motion and velocity ofThe SPARSE model is based on a combination of a truncated Taylor expansion of a drag correction function and Reynolds averaging.
