Summary on Grant Application Form |
|
a) To understand response mechanisms of cylinders in oscillatory flow b) To obtain an accurate data set of response characteristics for small scale cylinders c) To apply discrete vortex method with ciscous diffusion to predict response d) Validate vortex method for flexible cylinders against experimental results It is planned to perform a combined experimental and computational investigation into the in line and transverse response of flexible cylinders in oscillatory flow. The two components of the study will be carried out for an identical set of similarity parameters so that the two will be complementary and the results can be directly compared. The prime aim is to improve basic understanding of the fluid/structure interaction processes that occur when a flexible circular cylinder mounted in an oscillatory flow responds because of the generation and shedding of vortices. The unsteady, two dimensional Navier Stokes equations will be solved numerically using a discrete vortex formulation based on the cloud in cell method and including an algorithm to model viscous diffusion. Experiments will be performed in a U tube equipped with a pendulum suspension system which will ensure near two dimensional motion of the test cylinder and low structural damping. Circular cylinders with diameters of 10 mm and less will be used so that the viscous scale parameter is in a range where the numerical simulations can be expected to give reliable results.
