The onset of unsteadiness of two-dimensional bodies falling or rising freely in a viscous fluid: a linear study [PDF]

, 2012
We consider the transition between the steady vertical path and the oscillatory path of two-dimensional bodies moving under the effect of buoyancy in a viscous fluid.

Reproductive solution for grade-two fluid model in two dimensions

Revista Integración, 2009
We treat the existence of reproductive solution (weak periodic solution) of a second-grade fluid system in two dimensions, by using the Galerkin approximation method and compactness arguments.

Numerical Simulations of Turbulent Gas-solid Flow in a Gradual Expansion [PDF]

Journal of Applied Fluid Mechanics
Modeling efforts on turbulent gas-solid flows have mainly focused on studying particle-laden flows in channels and pipes. Despite its significance for industrial applications, the study of gas-solid flows in sudden or gradual expansions is less common in

Mathematical Model of Shale Oil Seepage at Micro-Nano Pore Scale

Energies, 2022
Due to the unclear seepage mechanism for shale oil, it is hard to establish a reasonable mathematical model to describe the flowing law. In this study, a real shale pore structure was reconstructed with CT scanning and a numerical model of fluid flowing ...
