Non-Linear Dynamics of Cylindrical Tubes in a Cross-Flow Heat-Exchanger.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
In this thesis, a mathematical model of a single flexible cylinder in an array of rigid cylinders subjected to cross-flow is studied. The flexible tube is subjected to an initial axial load and supported by loose supports. The instability and nonlinear dynamics of tubes planar motions are taken into consideration. Numerical results are obtained using a five-mode discretization of the governing equation. The results obtained thus indicate that, with high axial loads and flow velocities beyond certain critical values, the system can undergo flutter or buckling instability.
