Nonlinear Vibrations of Conical Shells with Concurrent Internal and External Flows, Ph.D. Dissertation Sharif University of Technology ; Dehghani Firouz Abadi, Ruhollah (Supervisor)
Abstract
In the current study, nonlinear vibration and stability of conical shells with both separate and concurrent internal and external flows are studied. External and internal flows are in the supersonic and subsonic regimes, respectively. The Krumhar’s aerodynamic piston theory is utilized to model the external loading on the structure as well as the compressible potential flow model to capture the internal fluid dynamics. The so-called compressible fluid model is obtained via simplification of the Navier-Stockes equations after applying the inviscid and irrotational assumptions. The nonlinear structural equations of motion are derived using the Hamiltonian dynamics approach and utilizing the...
