    6 Parallel Flow. Parallel flows enable a BPEL process to perform multiple tasks at the same time, which is especially useful when you need to perform several time-consuming and independent tasks. This chapter contains the following topics: Use Case for Parallel Flows. Overview of Parallel Flow Concepts. Defining a . non-parallel flow; if additional more used v 0 is imposed, the flow is conventionally called quasi-parallel flow. In the application which is contemplated and which involves the study of the stability of a three dimensional boundary layer of compressible flow over a flat Author: Y. Mérida, M. Jelliti, T. Lili.

Price New from Cited by: Genre/Form: Parallelstrom: Additional Physical Format: Online version: Betchov, Robert. Stability of parallel flows. New York, Academic Press, (OCoLC) In this chapter we wish to consider the stability of steady two-dimensional or axisymmetric flows with parallel streamlines.

Flows of this type were first studied experimentally by Reynolds (), who observed that instability could occur in quite different ways depending on. Genre/Form: Electronic books: Additional Physical Format: Print version: Betchov, Robert. Stability of parallel flows. New York, Academic Press, Kennedy et al.

[23] studied the onset of flow instability in copper microtubes of diameters and mm using degassed and deionized water as the fluid. To induce the flow instability, two different methods were adopted. Either flow rate was reduced from an initial high value, or. Stability of parallel flows in a microchannel after a T junction Article (PDF Available) in Physical Review E 72(6 Pt 2) January with Reads How we measure 'reads'.

The stability of the natural convection parallel flow in a vertical porous slab is reconsidered, by reformulating the problem originally solved. It is clear from this figure that in comparison to the results for the parallel flow theory, the non-parallel effects make the flow unstable at lower Reynolds numbers and for a wider range of frequencies.

Boiko, Alexander V. Dovgal, Genrih R. Grek, Victor V. Kozlov. The Lyapunov direct method is used to study the nonlinear stability of parallel convective shear flows of an incompressible fluid heated from below with stress-free boundaries.

In particular it is showed that plane Couette and plane Poiseuille flows with linear temperature profile are conditionally asymptotically stable, in a stronger norm than the “energy norm”, whenever the Rayleigh Cited by: 5. The Poiseuille flow in a circular pipe was studied by Sexl [55] with a conclusion of stability.

Prandtl [42] gave some discus-sions of the possible cause of instability in his article in the book "Aerodynamic Theory," edited by Durand.

The most extensive discussion of hydrodynamic stability seems to be the treat-ment of parallel flows by attempting to solve the eigen-value problem. The linear stability of parallel flow in a concentric annulus to infinitesimal, axially symmetric disturbances is considered.

First, the Poiseuille flow in annular cylinders is studied with the ratio k of the outer to inner cylinder as a parameter. The critical Reynolds number is a monotone function of this radius ratio, increasing without bound as k → ∞ (Hagen‐Poiseuille flow) from the Cited by: The book is written from the point of view intrinsic to fluid mechanics and applied mathematics.

The analytical aspects of the theory are emphasized. However, it has also been tried, wherever possible, to relate the theory to experimental and numerical results. Mechanisms of instability are considered along with fundamental concepts of hydrodynamic stability, the Kelvin-Helmholtz instability.

This chapter is followed by the four chapters of Part I, Temporal Stability of Parallel Shear Flows, which presents the authors’ view of the “fundamental topics underlying stability theory,” and the four chapters of the longer Part II, Stability of Complex Flows and Transition, which “covers more advanced topics.”Cited by: Stability of parallel flows is the basis of modern flow stability theory.

The Rayleigh theorem on inflectional instability is a fundamental theorem on inviscid stability theory. This theorem is found in many text books and employed in the scientific community since Rayleigh published his.

The global linear stability of incompressible, two-dimensional shear flows is investigated under the assumptions that far-field pressure feedback between distant points in the flow field is negligible and that the basic flow is only weakly non- parallel, i.e. that its streamwise development is slow on.

Linear spatial stability of the nonparallel developing flow in a rigid circular pipe has been studied at several axial locations for nonaxisymmetric disturbances. The main flow velocity profile is obtained by Hornbeck’s finite-difference method assuming uniform flow at entry to the by: 1.Home Browse by Title Theses Transient stability-constrained optimal power flow using improved differential evolution and parallel computing.
