This study presents Stereoscopic particle image velocimetry measurements of a precessing motion resulting from sudden expansion an axisymmetric jet into coaxial chamber. The has ratio 4.9 and aspect 2.03. velocity profile in the inlet tube is measured upstream using Laser doppler anemometry. Reynolds number (Re) varied 3160 to 63,870. time-averaged flow field exhibits behavior, near resembles t...

We discuss the potential information about highly excited QCD-matter provided by medium-induced partonic energy loss, known as " jet quenching ". In particular, with its large acceptance hadronic and electromagnetic calorimetry, the Compact Muon Solenoid detector at LHC collider is a promising device to study these effects. We present physics simulations of observables such as the jet distribut...

The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...

The energy and momentum lost by a hard parton propagating through hot and dense matter has to be redistributed during the nuclear medium evolution. Apart from heating the medium, there is the possibility that collective modes are excited leading to the emergence of Mach cones or Cherenkov radiation. Recent two-particle correlation measurements by STAR [ 1] and PHENIX [ 2] at RHIC indicate that ...

Vibrationally resolved electronic spectra are reported for the diatomic cations Tel and Bi: using the technique of resonance-enhanced photodissociation spectroscopy (REPD). These ions are generated by laser vaporization in a pulsed nozzle source, jet-cooled, mass-selected with a reflectron time-of-flight spectrometer, and dissociated on resonance with a tunable dye laser. Electronic excitation ...

This paper presents novel details on the dynamic behavior of human eyes (see Fig. 1). A high speed camera is used to capture the movement of the eye surface, which is excited by an air jet. For a group of subjects the dynamic response ends shortly after the excitation is over. For another group of subjects this first phase ends with a distinct offset in the displacement, which takes a significa...
