Numerical Simulation Of Tornado-Like Vortices, Diwakar Natarajan
Electronic Thesis and Dissertation Repository
The thesis investigates by numerical simulation the flow characteristics of tornado like vortices produced by three types of vortex generators, namely, Ward-type Tornado Vortex Chamber (TVC), WinDEEE Dome and Atmospheric Vortex Engine (AVE).
Laboratory scale (Ward-type TVC) tornado-like vortices were simulated for swirl ratios 0.1 to 2.0 using the CFD code Fluent 6.3. The simulations with Reynolds stress model compare well with past experimental results. Multiple vortices were observed for high swirl ratios in LES simulation. These simulations have generated a comprehensive benchmark data for future modelers and experimenters.
The effects of translation and surface roughness on laboratory scale tornado-like …
