in this paper, the turbulent air droplet flow inside a single passage of a curved type vane separator has been studied numerically. the simulation is based on the eulerian - lagrangian method. for turbulent air flow calculations, a computer code was developed to solve the reynolds averaged navier stokes (rans) equations together with the equations of reynolds stress transport model (rstm) on co...

in this study, fluid flow and energy separation in a micro-scale ranque-hilschvortex tube are numerically investigated. the flow is assumed as 2d, steady,compressible ideal gas, and shear-stress-transport sst k-w is found to be a bestchoice for modeling of turbulence phenomena. the results are in a good agreementwith the experimental results reported in the literature. the results show that flu...

We demonstrate that frustrated exchange interactions can produce exotic 3D crystals of vortex strings near the saturation field (H=H(sat)) of body- and face-centered cubic Mott insulators. The combination of cubic symmetry and frustration leads to a magnon spectrum of the fully polarized spin state (H>H(sat)) with degenerate minima at multiple noncoplanar Q vectors. This spectrum becomes gaples...

A low temperature relation R = Ωβ/4πμ between the radius R of a compactly supported 2D vorticity (plasma density) field, the total circulation Ω (total electron charge) and the ratio μ/β (Larmor frequency), is rigorously derived from a variational Principle of Minimum Energy for 2D Euler dynamics. This relation and the predicted structure of the global minimizers or ground states are in agreeme...

Considerable efforts are currently devoted to the preparation of ultracold neutral atoms in the strongly correlated quantum Hall regime. However, the necessary angular momentum is very large and in experiments with rotating traps this means spinning frequencies extremely near to the deconfinement limit; consequently, the required control on parameters turns out to be too stringent. Here we prop...
