Abstract
The current project consists on the calculation of the inertial particle trajectories in steady streaming flows, implementing the trajectory Maxey-Riley equation through a numerical method in Matlab software. The steady streaming flow is obtained by assuming small oscillation amplitude of an oscillating flow around a set of cylinders. The steady streaming velocity field is calculated through the FreeFem++, a finite element method software. A study of the Maxey-Riley equation is done, in which the different terms of the equation are explained. Using the Euler’s Method, the numerical trajectory is developed, choosing one cylinder configuration in order to do a study about the effects of varying parameters such as streaming Reynolds number, fluid-to-particle density ratio, the dimensionless oscillation amplitude and the particle-to-cylinder radius ratio in order to do a summary of the conditions in which the particles are trapped in the streaming flow.
