Nonlinear Vibrations of Coupled Current Carrying Beams Immersed in Fluid and Magnetic Field
, Ph.D. Dissertation Sharif University of Technology ; Dehghani Firouzabadi, Rohullah (Supervisor)
Abstract
In this project, the forced vibrations of a pair of strips carrying electric current inside the fluid have been analyzed. Euler-Bernoulli theory is used to model the structure and von-Karman strain is included in the structural equations. In terms of the degrees of freedom of the structure, the bending motion along with the twisting is defined for the current-carrying strips. In this way, the system has 4 degrees of freedom, whose equations are coupled to each other due to the mentioned assumptions. In order to model hydrodynamics and the forces corresponding to it, with the help of numerical simulation of the movement of the strip section inside the fluid (CFD analysis), the corresponding...
