The paper investigates the role of geometrical asymmetric modifications of a rectangular flat-backed body on the properties of the recirculating flow at a Reynolds number Re=1.8x10(5). The reference model has two reflectional symmetries denoted sy and sz in both spanwise directions. The flow is subjected to the static instability that leads to two mirrored wake states breaking the symmetry sy. Two families of geometrical variation of the fore-body and after-body are studied, each breaking one of the reflectional symmetries of the reference model. Geometrical modifications that preserve sy evidence possibilities of bistable dynamics suppression although the static instability persists. Geometrical modifications that do not preserve sy produces a large unbalance of both wake states in accordance to recent observations on real cars (Bonnavion et al. in J Wind Eng Ind Aerodyn 184:77-89, 2019). Results offer perspectives for potential drag reduction induced by appropriate coupling of bluff body geometry and wake state selection. [GRAPHICS]

A simple correlation to fit type I liquid-liquid equilibria (LLE) data is presented. Like the Hand plot (J. Phys. Chem. 1930, 24, 1961) and the correlation by Rod (Chem. Eng. J. 1976, 11, 105), it correlates the distribution;coefficients for e three components as a function of a scaling parameter that is a measure of the distance along the binodal from the binary end point to the plait point. It can be used to estimate the composition of the plait point and to interpolate and extrapolate data. It is also useful for estimating distribution coefficients for additional trace components (impurities that may build up in recycle around an extraction operation) when there is limited data. This correlation provides a fit that is comparable to or better than the fit obtained using the liquid activity coefficient models.
