A boundary-layer in a non-newtonian fluid
Zeitschrift für angewandte Mathematik und Physik ZAMP, 1961Dans ce memoire, on examine l'effet d'une variation de viscosite avec la vitesse de deformation dans une couche limite a deux dimensions. Pour des raisons mathematiques traitables, l'exemple que l'on etudie en detail est celui dans lequel le coefficient de viscosite est une fonction lineaire de la vitesse de deformation et la velocite du courant ...

A fluid can be defined as a material that deforms continually under the application of an external force. In other words, a fluid can flow and has no rigid three-dimensional structure. An ideal fluid may be defined as one in which there is no friction.

Magnetoplastic effect in non-Newtonian fluids.
AIAA Journal, 1966For thin shells, y can be approximated by unity, and Eq. (2a) adopts the identity of Eq. (1). Figure 1 shows the shell response history computed from Eq. (2) for three different loading rates for the unstable mode (m = 1, n = 30, Ref. 1). Comparison of these curves shows that, with fixed shell geometry, material, and load magnitude, the higher rate ...

Simple Non-Newtonian Fluid Flows
1980Publisher Summary This chapter focuses on simple non-Newtonian fluid flows. Water and air, the most important fluids for life, are Newtonian fluids. However, there are many fluid materials of importance in nature and technology that are non-Newtonian fluids. Certain aspects of the flow behavior of such non-Newtonian fluids are markedly different from

Stability of non-newtonian fluid flows
Journal of Applied Mechanics and Technical Physics, 2000The stability of non-Newtonian fluid films moving on inclined planes is studied within the two-parameter Ostwald-de Waele model with account taken of the surface tension and van der Waals forces. The problem is solved analytically in the linear formulation, and the evolution of finite-amplitude perturbations is determined numerically.

An approach to non-newtonian fluid mechanics
Journal of Non-Newtonian Fluid Mechanics, 1984This paper, being an essay submitted in competition for the Adams Prize in December 1964, is mainly devoted to Professor Oldroyd's fundamental ideas developed in a series of papers published in 1950-58. Various problems connected with the formulation of rheologically invariant equations of state in a convected as well as in a fixed coordinate system ...
