All-Sky Electrostatic Analyzer (A-ESA) is a scientific payload that will be mounted on lunar rover and designed to observe the variations of plasma environment Moon. A-ESA composed an electrostatic analyzer top, MCP assembly, power supply units electronics are located under it. has entrance scanning deflectors inner deflectors. The electrically scanned within ~90∘in vertical direction, i.e. hemi-spherical field view (FOV). When operating in observation mode, collection science data...
The convective heat transfer enhancement and deterioration of the supercritical hydrocarbon fuel in regenerative cooling channels a scramjet were investigated numerically. This study focused on suppression spiral rectangular with enhanced effects resulting from turbulence intensity induced flow. As result, compared straight channel, maximum temperature channel pitch 20 mm was reduced by 31.3%. Although cross-sectional shape area same, short had significant suppression. Furthermore, influence...
How to prescribe traction on boundary surface is still an open question in peridynamics. This problem investigated this paper. Through introducing the induced body force defined by traction, Silling's peridynamic motion equation extended a new formulation called traction-associated equation, which verified be compatible with conservation laws of linear momentum and angular momentum. The energy derived from has same form as that original peridynamics advanced Silling. Therefore, constitutive...
How to effectively control the coaxial stability of nano-bearings has an important influence on improving quality nano-bearings. Some relevant problems are studied in this paper. Firstly, we investigate basic non-coaxial modes double-wall carbon nanotubes (DWCNTs). On basis analysis for these modes, a planar continuum model is established according principle homogenization. By means model, dynamic parameter λ(*) characterizing determined. explicit function angular velocity and interlayer...
The contact angle and static equilibrium of the triple line a sessile droplet are investigated. New wetting equations derived by minimising total potential energy droplet. These differ from previous Young, Wenzel Cassie-Baxter. new show that is influenced edge local roughness at line, independent interfacial area within line. Through these equations, answers have been obtained to existing problems cannot be explained above-mentioned theories.
A representation of the non-local residual is issued in form theorem. This makes satisfy zero mean condition automatically. On basis this representation, a new theoretical framework and method to establish damage model are put forth. In framework, non-locality inelastic deformation characterized by residual, it need not introduce constitutive variables Helmholtz free energy dissipation potential. According method, quasi-brittle viscoplastic established. The equations evolution consistently...
In the benchmark problems of peridynamics, there are some eccentric results, for example, singularity uniaxial tension and anomalous dispersion wave. The reasons to give rise these results investigated. We calculated local wave an infinite rod after adding a divergence stress in peridynamic motion equation. acquired verify that solution problem all eliminated. Therefore, features solutions likely stem from lack characterizing contact interactions.
The Young-Laplace's equation is established based on liquid membrane without shearing resistance. It not valid for solid. By taking into account the in-plane and transverse within surface layer, we reconstruct so as to characterize of A new version proposed. shows that equilibrium solid determined by bulk stress, stress together. shear depends gradient Gaussian curvature strain. intrinsic cause residual stresses appear in interior only occurs non-spherical body.
Based on a energy flux vector associated with surface energy, the Lagrangian field theory is used to derive new mixed boundary condition of solid concerned effects. The prediction given by it agrees well experimental data lattice contraction palladium nanoparticles. Comparison various existing versions traction discussed. results show that version concise in and verifiable experiment.
