The onset and stability of a triple cross-diffusive viscoelastic fluid layer was investigated12. The rheology of viscoelastic fluid was approximated by the nonlinear Oldroyd-B constitutive equation which encompasses Maxwell and Newtonian fluid models as special cases. The stability of a triply diffusive...
=?100 based on the bulk fluid velocity and cylinder diameter. The relative amplitude of the periodic velocity perturbation was considered in the range 0.10–0.30 and the forcing frequency relative to the natural unforced shedding frequency was in the range 1.4–2.3. These choices yielded fixed ...
In addition, the resulting graph can be presented in the form of a Raimondi–Boyd graph, which can be easily used in the design and analysis of Bingham-fluid-lubricated journal bearings. Garg et al. [6] investigated the thermal and rheological effects of lubricants on the performance of slot...
