The detection of three-dimensional coherent vortical structures that get advected as well deformed with time is a challenge. However, it critical for the statistical analysis these vortices, example, quasi-streamwise vortices (QSVs) in near field turbulent shear layer, where cavitation inception typically occurs. These exhibit underlying correlations among different properties can be derived fr...

We derive the nonequilibrium kinetic equation describing the motion of chiral massless particles in the regime where it can be considered classically. We show that the Berry monopole which appears at the origin of the momentum space due to level crossing is responsible for the chiral magnetic and vortical effects.

The effect of streamwise plasma vortex generators on the convective heat transfer a turbulent boundary layer is experimentally investigated. A Dielectric Barrier Discharge (DBD) plasma-actuator array employed to promote pairs counter-rotating, streamwise-aligned vortices embedded in well-behaved over flat plate. study aims at elucidating mechanism interaction between plasma-induced vortical str...

In the present work we follow the breakdown of pairs of counter-rotating vortices (CVP) and the consequence formation of packets of hairpins in uniform shear flows. We employ a recent developed method which is capable of following (numerically) the evolution of finite-amplitude localized vortical disturbances embedded in shear flows. The solution is carried out using Lagrangian variables in Fou...

Controlling flow in an unsteady separating flow requires accurate information about the surface forces and the effect that vortical structures in the flow field have on those surface forces. A correlation between vortex passage and surface pressure is defined to determine appropriate locations for sensors on the surface of a square cylinder for control feedback. Data are generated using a large...

Energy-containing eddies (energy-eddies) are the elementary structures of wall turbulence that carry most kinetic energy and momentum. Despite consensus energy-eddies can self-sustain at each relevant length scale, their precise origin spatial evolution currently not well understood. In this study, we examine by quenching them inflow a turbulent channel flow. Our study shows involved in cascade...

The foundational differences of steady and unsteady jets issued into a laminar boundary layer crossflow are considered. Jets have been used widely for flow control applications, due to their ability enhance mixing mitigate separation, but it is unclear what role jet steadiness plays in effectiveness. Here we compare experimentally (synthetic) rectangular flat-plate with varying orifice pitch sk...

Abstract The paper investigated the benefits of having fins that induce swirling flow within an annular passage. importance vortical structures produced using different fin angles and velocities in heat transfer was studied. combination fluid with recirculation on domain not fully understood, this aims to address gap. 10°, 20°, 30° 40° angled were understand changes performance as becomes more ...
