The Design and Analysis of Bluff Body Dynamic Distortion Generators
… frequency determined by their Strouhal number. BeVERLI Hill is a geometry that has been extensively studied by Virginia Tech due to its unique, asymmetric vortex shedding that alternates chaotically off the back of the hill. Both of these types of bluff bodies were integrated with a base …
