WebA flow curve can be generated via predefined settings on the rotational viscometer/rheometer: The shear rate is increased step-wise with a defined measurement point duration for each point. The temperature and other ambient conditions are constant. The resulting flow curve shows the shear stress versus the shear rate. WebRayleigh flow refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible flow.
