## Abstract

This paper examines the detailed ‘ “Mayer structure of separated flow past a circular cylinder in a low-Rossby-number rotating fluid as the Ekman number E tends to zero. This structure is based on an initial proposal by Page (1987) but with some modifications in response to further evidence, outlined both in this paper and elsewhere, on the behaviour of E1/4-layer flows in this context. Numerical calculations for flow in an E1/4 shear layer along the separated free streamline are described and the mass flux from this layer is then used to calculate the higher-order flow within the separation bubble. The flow structure is found to have two forms, depending on the value of the 0(1) parameter A, and these are compared with results from published “Navier-Stokes” type calculations for the flow at small but finite values of E.
