Abstract: In its working state, the bit used in underwater horizontal directional drilling (UHDD) produces a high-frequency vibration that can affect accuracy of navigation. We designed a low-pass filter with linear phase on the ...

Abstract: Acoustic streaming generated from the travelingwave component of a synthesized sound field often has considerable influence on ultrasonic manipulations, in which the behavior of microparticles may be disturbed. In this ...

Abstract: The velocity, shape, and trajectory of the rising bubble in polyacrylamide (PAM) and carboxymethylcellulose (CMC) aqueous solutions were experimentally investigated using a set of homemade velocimeters ...

Abstract: In this paper, experimental investigation on two oil-soluble drag-reducing agents (DRAs) were carried out in stirred vessel by standard six-blade Rushton, based on the application of particle image velocimeter (PIV). Two ...
