An orthogonal superposition rotational rheometer that applies a rotational torque and an orthogonal axial oscillatory stress to a fluid. The rheometer uses a cylindrical bob in a double wall cup to apply shear rotational and axial forces to the fluid. Openings in the top section of the cylindrical bob reduce surface tension effects on the force measurement. Fluid pumping effects at the bottom of the rheometer's double wall cup are minimized by openings in the inner wall of the double wall cup that allow fluid to be displaced when the bob moves downwards.
