Evaluation Of The Aerodynamic Differences Of A Balloon Shape And A Sphere Using Computational Fluid Dynamic Modeling In Fluent, Daniel Burton Scholes
Evaluation Of The Aerodynamic Differences Of A Balloon Shape And A Sphere Using Computational Fluid Dynamic Modeling In Fluent, Daniel Burton Scholes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
While tracking balloons for wind characterization, there was a question about the theoretical rise rate and corresponding coefficient of drag of a balloon shape as compared to a sphere. Since there are many studies published detailing the drag on spherical shapes, the question of whether or not a balloon can be treated as a sphere begged to be answered.
In this study we apply Computational Fluid Dynamic (CFD) modeling to compare the aerodynamic behavior and drag of a sphere to that of a balloon as it moves through fluid at Reynolds numbers from 10,000 to 100,000.
Fluent CFD models are …
