Comparison of Acoustic Streaming Flow Patterns Induced by Solid, Liquid and Gas Obstructions

Micromachines, 2020
In this study, acoustic streaming flows inside micro-channels induced by three different types of obstruction—gaseous bubble, liquid droplet and solid bulge—are compared and investigated experimentally by particle tracking velocimetry (PTV) and ...

A New GRIME2: Using an Octagon Calibration Target and Trail Camera to Measure Stream Water Level Over a 2‐Year Period

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract GaugeCam Remote Image Manager Educational 2 (GRIME2) is a free, open‐source Windows application for water level measurement in surface water bodies using ground‐based time‐lapse imagery. We evaluated a new “stop sign” (i.e., octagon shape) calibration target and GRIME2 algorithms by comparing results to other measurement methods over a 26 ...

Experimental study on proppant placement in rough fractures with shear slippage in shale reservoirs [PDF]

Youqicang pingjia yu kaifa
Under the influence of fracture shear slippage and wall roughness, the fluid flow channels within the fractures are uneven, making the transport and placement patterns of proppant carried by fracturing fluids more complex.

Stereovision Combined With Particle Tracking Velocimetry Reveals Advection and Uplift Within a Restraining Bend Simulating the Denali Fault

Frontiers in Earth Science, 2018
Scaled physical experiments allow us to directly observe deformational processes that take place on time and length scales that are impossible to observe in the Earth’s crust. Successful evaluation of advection and uplift of material within a restraining

Validation of the granular temperature prediction of the kinetic theory of granular flow by particle image velocimetry and discrete particle model [PDF]

, 2004
In order to give a detailed description of the hydrodynamics in large industrial scale fluidized beds, continuum models are required. Continuum models often use the kinetic theory of granular flow (KTGF) to provide closure equations for the internal ...
