Aeroacoustics and Artificial Neural Network Modeling of Airborne Acoustic Emissions During High Kinetic Energy Thermal Spraying
(2019)This work describes an online, non-destructive monitoring technology for thermal spray coating processes based on the airborne acoustic emissions (AAE) in the booth. First, numerical simulations were carried out to probe ... -
Combining pressure management and energy recovery benefits in a water distribution system installing PATs
(2017)Gravity can play a beneficial role in certain water distribution networks (WDNs), although sometimes high nodal pressures occur. Excessive pressure may lead to several negative effects regarding the network's operation and ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Models of terms in the Reynolds stress budgets
(2017)In the first part of this study (Dritselis 2016 Fluid Dyn. Res. 48 015507), the Reynolds stress budgets were evaluated through point-particle direct numerical simulations (pp-DNSs) for the particle-laden turbulent flow in ... -
A general-purpose spray coating deposition software simulator
(2020)In this work the coating thickness from a high kinetic energy spray process is predicted as a function of the gun and object kinematics. The developed simulation package is capable of handling complex parts of arbitrary ... -
Numerical study of educed coherent structures in the near-wall region of a particle-laden channel flow
(2008)The interaction of small heavy solid particles with turbulence near the wall of a vertical downward channel flow is investigated by using direct numerical simulation (DNS) and Lagrangian particle tracking. The interest is ... -
Pressure Management and Energy Recovery Capabilities Using PATs
(2016)Hydro-turbines are widely used in small water energy production plants in order to turn water kinetic energy to electricity. PATs (Pumps working As Turbines) are micro-turbines (small sized compared to the usual ones) ... -
Results on the viscous slip coefficient for binary gas mixtures
(2008)The viscous slip coefficients for the binary gas mixtures of Ne-Ar, He-Ar and He-Xe are estimated by solving the McCormack kinetic model equation subject to Maxwell diffuse-specular scattering boundary conditions. The ... -
Simulation of gaseous microscale transport phenomena via kinetic theory
(2010)Kinetic theory of gases, as described by the Boltzmann or model kinetic equations, provides a solid theoretical approach for solving microscale transport phenomena in gases. Due to significant advancement in computational ... -
Whole-heart four-dimensional flow can be acquired with preserved quality without respiratory gating, facilitating clinical use: a head-to-head comparison
(2015)Background: Respiratory gating is often used in 4D-flow acquisition to reduce motion artifacts. However, gating increases scan time. The aim of this study was to investigate if respiratory gating can be excluded from 4D ...
