Abstract: Abstract We study the effects of fluid–particle and particle–particle interactions in a three-dimensional monodispersed reactor with unstable fluidization. Simulations were conducted using the immersed boundary method for particle Reynolds numbers of 20–70 with an Archimedes… read more here.

DOI: 10.1063/1.4997731
Abstract: We performed direct numerical simulations of decaying isotropic turbulence laden with finite-size particles using an immersed boundary method combined with a soft-sphere collision model. The particle diameter is about 25 times the Kolmogorov length scale,… read more here.
