The Coriolis tester, and especially its long specimen version, simulates well the slurry flow conditions in pumps, cyclones, pipes, etc. and provides a slurry erosion test mode that is closest to having well-defined particle–target impingement conditions. The predominance of glancing angle slurry impingement ensures that only a fraction of erodent particles has a normal component of impact velocity...
The Coriolis slurry tester provides a means of discriminating between the resistance of different materials to slurry erosion damage under low interaction intensity (low impingement angle and low normal velocity impact) conditions. A new design of the rotor-specimen holder assembly has been evolved to provide better control of the slurry flow over and along test specimen surfaces. Wear patterns on...
The Coriolis test is used for evaluating the slurry erosion behaviour of materials. Experiments with a model single glass bead-in-water ''slurry'' have revealed the nature of, and extent of damage at, all contact sites along a soft copper specimen surface. The results confirm previous theoretical predictions that in the Coriolis test mode erodent particles interact with the specimen in a series of...
The Coriolis erosion tester consists of a rotor with a diametrical passage in which two flat specimens are located equidistant from the centre. At high rotation speeds, slurry flows outwards from the centre by centrifugal force while the erodent particles are directed towards the specimen surfaces by the Coriolis force. This test mode offers a quick, simple and reproducible means of simulating the...
