Effect of Microscale Turbulent Structures Dynamics on Forced Convection in Turbulent Porous Media Flow
Ching-Wei Huang, Vishal Srikanth, Andrey V. Kuznetsov
The influence of microscale flow structures (smaller than the pore size) on turbulent heat transfer in porous media has not been yet investigated. The goal of this study is to dete…
Turbulent Microscale Flow Field Prediction In Porous Media Using Convolutional Neural Networks
Vishal Srikanth, Ching-Wei Huang, Ryan Harradine +1
Turbulence modeling in porous media can be greatly improved by combining high-resolution numerical methods with modern data-driven techniques. The development of accurate macroscal…
Turbulence Kinetic Energy Distribution and Heat Transfer in a Porous Layer Induced by Bluff Body Vortex Shedding
Thibaut K Kemayo, Justin Courter, Vishal Srikanth +3
When a turbulent vortex impinges on a porous layer, it creates a complex multiscale interaction: the wake structures that form in the free fluid engage with the intricate geometry…
Scale Collapse of Vortices at Porous-Fluid Interfaces
Justin Courter, Vishal Srikanth, Thibaut Kemayo +1
The interaction between externally generated turbulence and porous media is central to many engineering and environmental flows, yet the fate of macroscale vortical structures at a…
Instabilities and bifurcations in turbulent porous media flow
Vishal Srikanth, Andrey V. Kuznetsov
Microscale turbulent flow in porous media is conducive to the development of flow instabilities due to strong vortical and shearing flow occurring within the pore space. When the f…
Symmetry-breaking of turbulent flow due to asymmetric vortex shedding in periodic porous media
Vishal Srikanth, Andrey V. Kuznetsov
In this paper, we report new insight into a symmetry-breaking phenomenon that occurs for turbulent flow in periodic porous media composed of cylindrical solid obstacles with circul…
