Numerical study of the switching mechanism of a jet valve using the meshless method

Advances in Mechanical Engineering, 2021
This study numerically investigates fluid dynamics of a jet flow at supersonic speed. The meshless method and the overlapping point cloud method are used to handle the moving boundary problems.

Numerical Simulation of Particle Dynamics in a Spiral Jet Mill via Coupled CFD-DEM

Pharmaceutics, 2021
Spiral jet mills are ubiquitous in the pharmaceutical industry. Breakage and classification in spiral jet mills occur due to complex interactions between the fluid and the solid phases.

Jet–flap interaction tones

Journal of Fluid Mechanics, 2018
Motivated by the problem of jet–flap interaction noise, we study the tonal dynamics that occurs when an isothermal turbulent jet grazes a sharp edge. We perform hydrodynamic and acoustic pressure measurements to characterise the tones as a function of ...

Interfacial deformation and jetting of a magnetic fluid [PDF]

Computers & Fluids, 2016
An attractive technique for forming and collecting aggregates of magnetic material at a liquid--air interface by an applied magnetic field gradient was recently addressed theoretically and experimentally [Soft Matter, (9) 2013, 8600-8608]: when the magnetic field is weak, the deflection of the liquid--air interface has a steady shape, while for ...

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Jet mixing of fluids in tanks.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1982
An experimental investigation was made of the mixing of liquids in a tank where the liquid jet was injected through a nozzle. The mixing time was defined as the time required to reduce the concentration variation within 1% of the mixed mean value and was measured by an impulse response. The circulation time was also obtained from the response curve. It

Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

Advanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

A Decadal Survey Without Analogs: Earth Observation Needs for a Warming World

AGU Advances
Since 2007, the National Academy for Sciences Engineering and Medicine (NASEM) has recommended Earth Science research and investment priorities every 10 years. The Decadal Survey balances the continuation of essential climate variable time series against

Noncoalescence in the Oblique Collision of Fluid Jets [PDF]

Physical Review Letters, 2013
When two jets of fluid collide, they can "bounce" off each other, due to a thin film of air which keeps them separated. We describe the phenomenon of stable noncoalescence between two jets of the same fluid, colliding obliquely with each other. Using a simple experimental setup, we carry out a parametric study of the bouncing jets by varying the jet ...

Current Trends and Future Perspective for Cold Spray Metal‐Ceramic Composites

Advanced Engineering Materials, EarlyView.
The use of cold spray (CS) technology for creating cermet deposits, combining ceramic and metallic components, is advancing rapidly. Cermets offer excellent temperature handling and erosion resistance for diverse applications. This review outlines the current state of the art, focusing on the deposition dynamics and strategies to optimize the ...
