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: AbstractIt has been one of the most critical challenges to maintain a healthy, livable, and sustainable building environment. As part of such efforts, it is desired to efficiently inspect roofs that cover a large portion ...

Abstract: Abstract. During berthing, ships rely on auxiliary diesel engines for power, leading to suboptimal fuel efficiency and significant carbon emissions that compromise port air quality and public health. This article proposes ...

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 ...
