ABSTRACT
Research in orbital space flight is using to a large extent the fact that gravity is compensated by the spacecraft’s free fall around the globe. Reducing gravity to a minimum has great advantages with respect to the decrease in mechanical forces, decreased convection, buoyancy, hydrostatic pressure, etc. Centrifuges/hypergravity is used in both life and physical sciences. One of the side effects, or artifacts, of rotating systems, like gravity generated in a centrifuge, is the Coriolis effect. The extend of the Coriolis effect on a sample depends on the axes along which the object moves with respect to the rotation axes. Besides the inertial shear due to lateral forces, one also has to take into account an artifact in the axial direction: the gravity gradient.
