A theoretical study on the unsteady aerothermodynamics for attached flow models
Science China Physics, Mechanics & Astronomy - Tập 53 - Trang 1505-1514 - 2010
The principle of the unsteady aerothermodynamics was theoretically investigated for the attached flow. Firstly, two simplified models with analytic solutions to the N-S equations were selected for the research, namely the compressible unsteady flows on the infinite flat plate with both time-varying wall velocity and time-varying wall temperature boundary conditions. The unsteady temperature field ......
Local Reynolds number and thresholds of transition in shear flows
Science China Physics, Mechanics & Astronomy - Tập 56 - Trang 263-269 - 2013
Recent experimental and numerical investigations reveal that the onset of turbulence in plane-Poiseuille flow and plane-Couette flow has some similar stages separated with different threshold Reynolds numbers. Based on these observations and the energy equation of a disturbed fluid element, a local Reynolds number Re
L is derived to represent the maximum ratio of the energy......
Uncovering the magnetic response of open-shell graphene nanostructures on metallic surfaces at different doping levels
Science China Physics, Mechanics & Astronomy - Tập 67 - Trang 1-7 - 2024
Open-shell graphene nanostructures (GNs) are promising candidates for future spintronics and quantum technologies. Recent progress based on on-surface synthetic approach has successfully created such GNs on metallic surfaces. Meanwhile, the doping effect of metallic surfaces is inevitably present and can significantly tune their electronic and magnetic properties. Here, we investigate the zigzag e......
The robustness of contextuality and the contextuality cost of empirical models
Science China Physics, Mechanics & Astronomy - Tập 59 - Trang 1-10 - 2016
In this paper, we introduce and discuss the robustness of contextuality (RoC) R
C
(e) and the contextuality cost C(e) of an empirical model e. The following properties of them are proved. (i) An empirical model e is contextual if and only if R
C
(e) > 0; (ii) the Ro......
Optical and photo-carrier characterization of ultra-shallow junctions in silicon
Science China Physics, Mechanics & Astronomy - Tập 56 - Trang 1294-1300 - 2013
Spectroscopic ellipsometry (SE), photocarrier radiometry (PCR) and photoluminescence (PL) techniques were employed to measure the ultra-shallow junction (USJ) wafers. These USJ wafers were prepared by As+ ion implantation at energies of 0.5–5 keV, at a dose of 1×1015 As+/cm2 and spike annealing. Experimentally the damaged layer of the as-implanted wafer and the recrystallization and activation of ......

Exploring neutrino mass and mass hierarchy in interacting dark energy models
Science China Physics, Mechanics & Astronomy - Tập 63 - Trang 1-9 - 2019
We investigate how the dark energy properties impact the constraints on the total neutrino mass in interacting dark energy (IDE) models. In this study, we focus on two typical interacting dynamical dark energy models, i.e., the interacting w cold dark matter (IwCDM) model and the interacting holographic dark energy (IHDE) model. To avoid the large-scale instability problem in IDE models, we apply ......
