Starting Jets and Vortex Ring Pinch-Off

Gao, L.; Yu, S. C. M.

Pages: 1 –31

[Starting jet is commonly defined as the transient motion produced when a viscous incompressible fluid is forced from an initial state of rest Cantwell (Journal of Fluid Mechanics, 173, 159–189 [6]). The applied force can be time dependent in the form of an impulsive, step or ramp function acting...

The Impact of a Vortex Ring on Porous Surfaces—A Review

Lim, T. T.; Adhikari, D.

Pages: 33 –60

[A vortex ring interacting with a solid surface have been studied extensively, both experimentally and numerically, for many years, however, there are relatively few studies made on the interaction with porous surfaces. Most of these studies were carried out recently and limited to laboratory...

Experimental Studies of the Near-Field Spatio-Temporal Evolution of Zero-Net-Mass-Flux (ZNMF) Jets

Soria, J.

Pages: 61 –92

[This chapter describes the results of an investigation of the near-field spatio-temporal evolution of a zero-net-mass-flux (ZNMF) jetZero-net-mass-flux jet at Re = 13,329 and a St = 0.03. This ZNMF jet has been found to be a turbulent jet in the far field (da C Andrade in On the circulations...

Simulation and Modeling of Synthetic Jets

Tang, H.; Zhong, S.

Pages: 93 –144

[This chapter gives a comprehensive review on the state-of-the-art numerical simulation and modeling of synthetic jet (SJ), an oscillatory, zero-net-mass-flux jet that has great potential in flow control. The numerical techniques dealing with the SJ oscillation, laminar-turbulent transition, and...

Dynamics of Jets Issuing from Trailing-Edge Modified Nozzles

New, T. H.; Tsovolos, D.; Tsioli, E.

Pages: 145 –189

[This chapter will elaborate upon the fundamental flow behaviour associated with vortex-rings and jets issuing from nozzles, where the nozzle trailing-edges or lips are physically modified with selected geometries. This technique represents a passive but robust form of manipulating the underlying...

Impinging Jets

Tesař, V.

Pages: 191 –231

[This Chapter summarises existing knowledge about near field of fluid jets impinging upon a solid wall. In particular, the chapter focuses attention on submerged jets (those having the same density as the surrounding more or less stationary outside fluid) in which the impingement is complicated...
