The concept of fluid “yield” is important but controversial since it was proposed. Traditionally, when the applied stress is larger than a critical value, the deforming solid began to show liquid-like behavior. This critical value of stress is na

This paper presents a study of the finite depth Stokes’ first problem for a thixotropic layer. The yield behavior of the thixotropic fluid in this problem is investigated for the first time. The main physical features of this problem are discussed,

The linear stability of wall-injected pressuredriven Couette-like flow in power-law fluids is studied. Previous study on this kind of flow for Newtonian fluids by Nicoud and Angilella [Phys. Rev. E 56, 3000 (1997)] was extended to power-law fluids to

It is well known that plane creeping Couette flow of UCM and Oldroy-B fluids are linearly stable. However, for Burges fluid, which includes UCM and Oldroyd-B fluids as special cases, unstable modes are detected in the present work. The wave speed, cr

The long wave stability of core-annular flow of power-law fluids with an axial pressure gradient is investi- gated at low Reynolds number. The interface between the two fluids is populated with an insoluble surfactant. The an- alytic solution for the

The linear stability of plane Poiseuille flow of Burgers fluid at very low Reynolds numbers is studied. In the previous works, it was shown that plane Poiseuille flows of UCM and Oldroyd-B fluids at very low Reynolds numbers are linearly stable. Howe

A fractional-order Maxwell model is used to describe the viscoelastic seabed mud. The experimental data of the real mud well fit the results of the fractional-order Maxwell model that has fewer parameters than the traditional model. The model is then

The effect of an insoluble surfactant on the flow instability of two upper convected Maxwell (UCM) fluid co-extrusion flow in a circular pipe is studied using a linear normal-mode and complementary energy analysis. The influences of surfactant and fl

In this paper, the axial Couette–Poiseuille flow of Bingham fluids through concentric annuli is studied. Analytical solutions of different types of flow are derived. Compared to previous studies, we emphasize two new types of flow, which have been
