In this study, a new image calibration approach is presented that corrects arbitrary optical distortions by utilizing non-parametric, 3D disparity fields. A calibration plate with a high spatial resolution (i.e., high density of calibration marks) wa

The pressure field of an impinging synthetic jet has been computed from time-resolved, three-dimensional, three-component (3D-3C) particle image velocimetry (PIV) velocity field data using a Poisson equationbased pressure solver. The pressure solver

Studies concerning the influence of fluidizing air on the gas–solid flow that occurs when a high-speed jet is injected into a fluidized bed have been limited to the measurement and analysis of mean velocity profiles. This study presents Laser Doppl

A Laser Doppler Velocimetry (LDV) technique was implemented to simultaneously measure the gas and particulate phase velocities in a high-speed jet plume in a two-dimensional (2D) bubbling fluidized bed. The gas and particulate phase velocity profiles

In the present work, the effect of emulsion fluidization on the gas and particle phase transport in a high-speed gas jet plume in a bubbling bed is examined. Implementing a Laser Doppler Velocimetry (LDV) technique, the gas and particulate phase velo

A laser Doppler Velocimetry (LDV) technique has been developed to simultaneously measure the gas and particulate phase velocities in a high-speed jet plume in a 2D bubbling fluidized bed. The laser, optics, and signal processing filters were configur

Unprotected skin and external surfaces of a spacecraft in earth orbit may experience temperature variations from −50°C to +100°C during exposure to cold space or sun. As a result, thermal management of spacecraft becomes extremely important. One

In most laser Doppler velocimetry (LDV) systems, the frequency of one of the two laser beams that intersect to create the probe volume is shifted with an acousto-optic element. It is shown here that Bragg shifting can impose a problematic fluctuation
