Abstract

A measurement method of measuring the unsteady flow of velocity of a fluid, characterized by the fact that it comprises the following steps: i) detecting instants at which the acceleration of the fluid is zero; ii) defining a measurement of the fluid velocity at instants where the acceleration is zero; and iii) determining changes in velocity between instants of zero acceleration by numerically integrating the difference between two static pressures.
