Annular flow of viscoelastic fluids: Analytical and numerical solutions

This work provides analytical and numerical solutions for the linear, quadratic and exponential Phan–Thien–Tanner (PTT) viscoelastic models, for axial and helical annular fully-developed flows under no slip and slip boundary conditions, the latter given by the linear and nonlinear Navier slip laws. The rheology of the three PTT model functions is discussed together with the influence of the sli...

Electro-osmotic and pressure-driven flow of viscoelastic fluids in microchannels: Analytical and semi-analytical solutions

Journal of Fluids Engineering Editorial Policy

Although no standard method for evaluating numerical uncertainty is currently accepted by the CFD community, there are numerous methods and techniques available to the user to accomplish this task. The following is a list of guidelines, enumerating the criteria to be considered for ar-chival publication of computational results in the Journal of Fluids Engineering. 1. Authors must be precise in...

Unsteady flow organization of compressible planar base flows

The unsteady flow features of a series of two-dimensional, planar base flows are examined, within a range of low-supersonic Mach numbers in order to gain a better understanding of the effects of compressibility on the organized global dynamics. Particle image velocimetry is used as the primary diagnostic tool in order to characterize the instantaneous near wake behavior, in combination with dat...

Modeling of Unsteady Forces on Particles in Compressible Flow

The unsteady force on particles in viscous compressible flows is studied. Based on earlier work by Parmar et al. (Phil. Trans. Roy. Soc. A, 366, 2161-2175, 2008) on the behavior of the unsteady force on particles in inviscid compressible flows, a simple model for the unsteady force at finite Mach and Reynolds numbers is proposed. This model involves a composite kernel that consists of the addit...
