... and the measurements of local characteristics. The measurements of local characteristics were performed with a hot-wire anemometry and a five-hole probe. Reduction in adverse flow conditions near the trailing edge at the tip of the hollow blade, boundary-layer reduction in the hollow blade suction side, and reduction...

...Sergey P. Bardakhanov; Sang W. Joo A new technique for velocity-field measurements in fine granular systems is introduced. The hot-wire anemometry, mainly used for gaseous flows, is applied to nanopowders and is found to be a viable experimental method for flow measurements. A generic chute flow...

...J. C. Hu; Y. Zhou The wake of asymmetric bluff bodies was experimentally measured using particle imaging velocimetry, laser Doppler anemometry, load cell, hotwire, and flow visualization techniques at Re = 2600 – 8500 based on the freestream velocity and the characteristic height of the bluff...

... the blades’ pitch angle over the turbulent structures is assessed by means of turbulence intensity values and integral length scales, obtained by using hot-wire anemometry for several test conditions. Since total unsteadiness is composed of both periodic and random unsteadiness, it is necessary to filter...

Detailed measurements of the flow field were obtained using hot-wire anemometry in a traverse sector that covered the whole...

... description of the flow across the turbomachine. Using hot-wire anemometry, measurements of axial and tangential velocities were carried out in two transversal sectors: one between the rows and the other downstream of the rotor, covering the whole span of the stage for a complete stator pitch. Ensemble...

With an increase in frequency, the recirculation length substantially reduces and diminishes the time-averaged drag coefficient...

...Nan Gao; Dan Ewing The development of the flow field produced by concentric jets used in the blown-film manufacturing process was studied experimentally using hot wire anemometry. It was found that the inner jet was entrained into the outer jet before the outer jet attached to the wall. The inner...

..., as is typically found within the approach flow of these systems, can also affect the time dependent jet and flow field generated by the port. Measurements using both hot wire anemometry (HWA) and a three component Laser Doppler Anemometry (LDA) system were therefore used to characterize the flow field. Cross...

...Stephen A. Huyer; Stephen R. Snarski The unsteady turbulent inflow into a swirl-inducing stator upstream of propeller (SISUP) propeller is presented. The upstream stators and hull boundary layer generate a complex, three-dimensional inflow that was measured using x-wire anemometry. High resolution...
