Definition Coriolis Force u An apparent deflection of the path from an object that moves within a rotating system u Definition by Gustave-Gaspard Coriolis (1835) INSA 15 / 14
Coriolis Force Example u In the inertial frame of reference the black object moves in a straight line. u However, the observer (red dot), who is standing in the rotating (non-inertial) frame of reference, sees the object as following a curved path due to the Coriolis and centrifugal forces present in this frame. INSA 16 / 14
Coriolis Effect Demonstration u No flow: hose is in balance u Flow: out of balance (distortion of the hose) causing a phase shift between in- and outlet. INSA 17 / 14
