Estudio experimental de las fuerzas hidrodinámicas que actúan en una pila de puente rectangular de acuerdo al ángulo de incidencia al flujo

Abstract

This research presents an estimate of drag and lift forces acting on a rectangular bridge pier with width-length ratio of 2-3 and 1-2 in its cross-section, for angles of incidence to flow in a range from 0 to 60 degrees. These forces were determined with a series of experiments in which the pressure was measured around the surface of the pier. These experiments were done in a rectangular channel, with three different flow velocities, Reynolds numbers between 6,02x103 to 5,59x104 and with a subcritical flow rate in all cases. As results, the variation of both forces and drag and lift coefficients obtained in each of the tests is presented.
