Analysis of Cylinder Vibration and Hydrodynamic Forces Project

This project investigates the dynamics of a cylinder subjected to hydrodynamic forces, focusing on vibration and power extraction. Part one presents an energy extraction device comprised of a cylinder elastically mounted to an electric generator, analyzing the impact of the Keulegan-Carpenter number (KC) and damping coefficient (c) on displacement, vibration velocity, and extracted power. A MATLAB simulation using the fourth-order Runge-Kutta method is employed to solve the governing equations of motion, considering both steady and oscillatory flow. The results demonstrate the relationship between KC, damping, and power output, with graphical representations and tabular data illustrating the effects of varying parameters. Part two extends the analysis to a square cylinder, examining the hydrodynamic forces acting upon it. The project provides a comprehensive understanding of the forces involved and the influence of key parameters, crucial for designing structures in water environments. The project concludes by highlighting the importance of these principles in the design of various structures such as dam walls, offshore structures and oil mining machines. The project provides a detailed understanding of the forces involved and the influence of key parameters.
