"WebTaylor-Couette flow, the flow between two coaxial co- or counter-rotating cylinders, is one of the paradigmatic systems in the physics of fluids. The (dimensionless) control parameters are the Reynolds numbers of the inner and outer cylinders, the ratio of the cylinder radii, and the aspect ratio. One key response of the system is the torque required to retain constant … " - Rayleigh drag

A linear formulation of drag was first introduced as the Guldberg-Mohn approximation of virtual internal friction in 1876 (Neumann, 1968). Now known as Rayleigh drag, the approximation describes drag within a fluid that is proportional and opposite to the fluid’s velocity.

Websurface drag (Chen et al., 2007; Mbengue & Woollings, 2024). Robinson (1997) showed this to be caused by the Rayleigh drag acting on the mean flow rather than the eddies and argued that friction changes how the zonal wind responds to eddy forcing. Note that a convenient feature of the linear Rayleigh drag is that in

Webels commonly include a Rayleigh drag throughout the model domain, and three-dimensional models commonly include a Rayleigh drag or diffusive sponge layer in the upper portion of the model domain.
