Principles of centrifuge modeling SERIES

Centrifugal Acceleration The easiest way to create high gravity is by spinning our soil models in a centrifuge. When the centrifuge is rotating with an angular velocity of 'ω', the centrifugal acceleration at any radius 'r' is given by centrifugal acceleration = r ×ω2 We wish to match this centrifugal acceleration to be the same factor
