“…This method is shown to be accurate and numerically convergent (Garg et al, 2010;Tenneti et al, 2011). In addition, PUReIBM has been successfully used to simulate fixed particle assemblies (Tenneti et al, 2010(Tenneti et al, , 2011Sun et al, 2015) and freely evolving suspensions of monodisperse gas-solid flows (Subramaniam et al, 2014;Mehrabadi et al, 2015;Tenneti et al, 2016).…”
