The artificially submerged cavitation water jet is effectively utilized by ejecting a high-pressure stream into low-pressure through concentric nozzles and utilizing the phenomenon generated shear layer formed between two streams. In this study, we investigated characteristics of jets combining numerical simulations erosion experiments. results indicate that an appropriate standoff distance can generate more clouds on workpiece surface, are most pronounced at dimensionless SD = 30. effect...
Efficient internal mixing stands as a pivotal requirement for droplet-based micro-reactors/micro-mixers facilitated by microfluidic systems. Among the various methods their production, capillary-generated droplets emerge notable approach. Understanding role of coaxiality within coflow devices in influencing remains crucial aspect optimizing these Coaxiality inserted cylindrical capillaries significantly affects efficiency according to our experimental observations. Through numerical...
Nanomaterials have great potential to influence the properties of cement-based materials due their small particle size and large specific surface area. The influences Nano-SiO2 (NS), gamma-nano-Al2O3 (GNA), alpha-nano-Al2O3 (ANA), nano-TiO2 (NT) on rheology hydration kinetics class G cement at 30 °C were investigated in this study. nanomaterials added dry powder form dosages 1, 2, 3, 5, 7% by weight (bwoc), dispersion was accomplished using polycarboxylate superplasticizer (PCE) a dosage...
Hydrophobic biodegradable ethyl cellulose (EC) nanoparticles are commonly used to stabilize the gas/liquid interfaces. To produce EC foams, ultrasonication with a driving frequency of 21.45 kHz is utilized. suspension reduced cavitation noise, and immersing depth vibrating horn influenced foamability particles. When near air/liquid interface, dense homogeneous foams will be obtained, but when bottom wall, sparse polydisperse obtained. This attributed fact that more bubbles stabilized by in...
The cavitation noise in the ultrasonic vibration system was found to be influenced by size of microparticles added water. SiO2 with diameter smaller than 100 μm reduced noise, and reason attributed constrained oscillation bubbles, which were stabilized microparticles.
In ultrasonic cavitation, iridescent rings always occur around erosion pits on steel surface. These colorful halos can reflect the experienced temperature of surface, but reason for their formation is controversial. this study, development an pit and ring it stainless (1Cr18Ni9Ti) surface was numerically investigated based energy transformation theory. The results revealed that areas with shape three-dimensional hemisphere could reach as high 1685 K, position material's highest exactly at...
Abstract This paper presents the mechanical design, modeling, and experimental behavior of a novel biomimetic robot inspired by water striders, which are six-legged insects that move on propelling themselves using two mesothoracic legs supporting with four other legs. As surface tension is too low for to carry heavy equipment, hollow elongated ellipsoids used as Relative screw propeller, rowing cause less turbulence in water. Because this can operate various environments, such windy lake,...
In this paper, a computational fluid dynamics (CFD) calculation was used to evaluate the effects of inlet feed flow rate and concentration fluctuations on hydrocyclone's separation performance. A mixture model multiphase flows, while Reynolds stress (RSM) modeled turbulence in inner field dynamic hydrocyclone. After numerical investigation, it is found that when at below certain value, favorable efficiency obtained with some most likely resulted from influence wall high rotary speed. When...
Terrain monitoring of intertidal beach is important to the coastline evolution research. Due complexity environment and dynamics terrain changes, in situ, real-time, long-term topography are big difficulties for existing observation methods.

Noise from the cavitation around propellers is main noise source of marine vehicles. In our experiment, we found that material propeller also affected noise, especially on their frequencies. Three most commonly used metal materials, including brass (B), aluminum bronze (AlB), and stainless steel (SS), were placed in an ultrasonic system. They presented different spectral peaks measured spectrum, one with higher elastic modulus has a frequency. According to numerical validation, this...
