A Study of the Effects of Tornado Translation on Wind Loading Using a Potential Flow Model

Autor: Shuan Huo, Jin Wang, Fred L. Haan, Gregory A. Kopp, Mark Sterling

Publikováno v: Frontiers in Built Environment, Vol 8 (2022)

This paper investigates the effects of tornado translation on pressure and overall force experienced by an airfoil subjected to tornado loading and presents a framework to reproduce the flow conditions and effects of a moving tornado. A thin symmetri

Critical wind speeds for tornado-induced vehicle movements

Autor: Derek A. Stedman, Fred L. Haan, Gregory A. Kopp, Partha P. Sarkar

Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 168:1-8

Little is known about how tornadoes move (parked) vehicles, although they are one of the most commonly observed examples of tornado damage. In this study, models of vehicles were tested in a laboratory tornado simulator and in a boundary layer wind t

Publikováno v: Journal of Wind Engineering and Industrial Aerodynamics. 138:27-35

Thunderstorms and related tornadoes caused over $25 billion in damages in 2011, the majority of which occurred to residential structures. Over 13,000 homes were damaged or destroyed by two tornadoes in Tuscaloosa and Joplin alone. Such substantial lo

An Examination of Static Pressure and Duration Effects on Tornado-Induced Peak Pressures on a Low-Rise Building

Autor: Fred L. Haan

Publikováno v: Frontiers in Built Environment. 3

This study investigated the role of duration and tornado-induced static pressure on peak pressures on a low-rise building. A tornado simulator was used to generate both translating and stationary vortices to measure pressure time series on a building

Correlation Structures of Pressure Field and Integrated Forces on Oscillating Prism in Turbulent Flows

Autor: Fred L. Haan, Ahsan Kareem, Teng Wu

Publikováno v: Journal of Engineering Mechanics. 142

This study sought to illuminate the turbulence-induced changes in the aerodynamic correlation structure on a stationary/oscillating rectangular prism. A forced-vibration system was used with a model instrumented with 66 pressure transducers. The stud

Characterization of the wind loads and flow fields around a gable-roof building model in tornado-like winds

Autor: Hui Hu, Fred L. Haan, Partha P. Sarkar, Zifeng Yang

Publikováno v: Experiments in Fluids. 51:835-851

An experimental study was conducted to quantify the characteristics of a tornado-like vortex and to reveal the dynamics of the flow-structure interactions between a low-rise, gable-roof building model and swirling, turbulent tornado-like winds. The e
