A Data-Driven Neural Network Model to Correct Derived Features in a RANS-Based Simulation of the Flow Around a Sharp-Edge Bluff Body
DownloadSpring 2023
In this dissertation, a machine-learning method is utilized to enhance the accuracy of wake parameters calculated by Reynolds Averaged Navier Stokes (RANS) k-ω SST model of flow on and around wall-mounted rectangular cylinders. Using high-quality results from Large Eddy Simulation (LES), this...

This dissertation characterizes the wake dynamics of long depth-ratio wall-mounted rectangular cylinders at a range of Reynolds numbers between 250-1000 at different incidence (yaw) angles, 0° - 45° with respect to the free stream flow. The effect of large depth-ratio on flow characteristics and...

Abstract In this study a complete solution methodology is developed for the simulation of hydrocyclones. A commercial software package, Ansys 12 Fluid Dynamics (Fluent), is used to solve the governing conservation equations. Turbulence is modelled using the large eddy simulation, and the...

This thesis experimentally and numerically examines the physical processes of a turbulent descending (ascending) plume in a two-layer stratified ambient fluid with and without background rotation. At the initial time, $t=0$, the plume either penetrates through or spreads along the ambient...
