in this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. to do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at reynolds number 45500 were accurately...

The function of the heterocercal tail in sharks has long been debated in the literature. Previous kinematic data have supported the classical theory which proposes that the beating of the heterocercal caudal fin during steady horizontal locomotion pushes posteroventrally on the water, generating a reactive force directed anterodorsally and causing rotation around the center of mass. An alternat...

Squids use a pulsed jet and fin movements to swim both arms-first (forward) and tail-first (backward). Given the complexity of the squid multi-propulsor system, 3D velocimetry techniques are required for the comprehensive study of wake dynamics. Defocusing digital particle tracking velocimetry, a volumetric velocimetry technique, and high-speed videography were used to study arms-first and tail...

Diffusion wake is an unambiguous part of the jet-induced medium response in high-energy heavy-ion collisions that leads to a depletion soft hadrons opposite direction jet propagation. New experimental data on $Z$-hadron correlation Pb+Pb at Large Hadron Collider show, however, enhancement both $Z$ and jet. Using coupled linear Boltzmann transport hydro model, we demonstrate modification partons...

A turbulent axisymmetric bluff body wake is investigated using large eddy simulation to uncover key flow dynamics and structures. The effect of low-frequency high-frequency pulsed jet forcing at the point separation studied reveal underlying mechanisms involved in base pressure changes, which provide a reference for drag reduction active control.

the aerodynamics of road vehicles has frequently been studied in simplified geometries to separate the effect of various components on aerodynamic drag and on near wake flow dynamics. in this work, the characteristics of the near wake of a notch-back car model were investigated, using hot-wire anemometer. the main objectives of this study are to gain a better understanding of the flow structure...
