A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

Creator:

Finn, Justin Richard

Abstract:

In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...

A multiscale modeling approach for bubble-vortex interactions in hydro-propulsion systems

Creator:

Finn, Justin Richard

Abstract:

Multiphase flow dynamics are important in many naval and turbomachinery applications, where bubble interaction with low pressure, vortical structures can lead to undesirable cavitation effects. To better understand the underlying phenomena, a multiscale numerical framework is developed to simulate bubble laden flow in dynamic hydro propulsion systems. Several subproblems in...
