Flow and thermal fields investigation in divergent micronano channels

open access: yesJournal of Thermal Engineering, 2016
The present work is related to the study of the nitrogen gas flow through diverging micro/nano-channels. The direct simulation Monte-Carlo (DSMC) method has been used to study the flow.

TRANSITION IN THE FRETTING PHENOMENON [PDF]

open access: yesFiabilitate şi Durabilitate, 2022
Fretting regimes were first mapped by Vingsbo. In a similar way, three fretting regimes will be considered: stick regime,slip regime and mixed regime.

Explaining Myanmar's Regime Transition: The Periphery is Central [PDF]

open access: yes, 2014
In 2010, Myanmar (Burma) held its first elections after 22 years of direct military rule. Few compelling explanations for this regime transition have emerged.

Cold-to-warm flow regime transition in snow avalanches [PDF]

open access: yesThe Cryosphere, 2018
Large avalanches usually encounter different snow conditions along their track. When they release as slab avalanches comprising cold snow, they can subsequently develop into powder snow avalanches entraining snow as they move down the mountain. Typically,

Bubble Column Reactors: the Variables Influencing the Mono-dispersed Homogeneous Flow Regime

open access: yesChemical Engineering Transactions, 2023
The fluid dynamics of large-diameter bubble columns explicates in six flow regimes emergin upon an increase in the gas flow rate and can be described and predicted via correct modelling of the flow regime transition coordinates. This study focuses on the

Modelling Thermally Induced Non-Equilibrium Gas Flows by Coupling Kinetic and Extended Thermodynamic Methods

open access: yesEntropy, 2019
Thermally induced non-equilibrium gas flows have been simulated in the present study by coupling kinetic and extended thermodynamic methods. Three different types of thermally induced gas flows, including temperature-discontinuity- and temperature ...

Modelling thermal flow in a transition regime using a lattice Boltzmann approach [PDF]

open access: yes, 2007
Lattice Boltzmann models are already able to capture important rarefied flow phenomena, such as velocity-slip and temperature jump, provided the effects of the Knudsen layer are minimal.

Autonomy as Anticipation of the World of Work at School

open access: yesSwiss Journal of Sociology, 2019
Schools are under increasing pressure to prepare students for the transition to post-compulsory education and vocational training. Beyond the support of the students’ professional orientation, the focus is on students’ learning of soft skills.
