Autor: Lakshmi Srinivasan, Nishanth Ram, Sudharshan Bharatwaj Rengarajan, Unnikrishnan Divakaran, Akram Mohammad, Ratna Kishore Velamati
Publikováno v: Energies, Vol 16, Iss 5, p 2250 (2023)
Vertical Axis Wind Turbines (VAWTs) have proven to be suitable for changing wind conditions, particularly in urban settings. In this paper, a 2D URANS (Unsteady Reynolds-Averaged Navier Stokes) numerical analysis is employed for an H-Darrieus VAWT. A

Towards a high resolution view of infrared line formation
Autor: Montelius, Martin, Ryde, Nils, Jönsson, Henrik
We have used H band spectra from IGRINS (R ~45000) of 34 K giants to investigate the limits of infrared spectroscopy. The principal question is: to what extent do abundances derived from infrared spectra agree with optical values, and which aspects o

Dynamical circulation regimes in planetary (and exo-planetary) atmospheres
Autor: Tabataba-Vakili, Fachreddin
In this thesis, we study the effect of diurnally- and seasonally-varying forcing on the global circulation of planetary atmospheres explored within a large parameter space. This work focusses on studying the spacial and spectral energy budgets across

Anisotropic turbulence and Rossby waves in an easterly jet: An experimental study
Autor: Boris Galperin, Jesse Hoemann, Stefania Espa, Gabriella Di Nitto
Publikováno v: Geophysical Research Letters. 41:6237-6243
A westward propagating jet is investigated experimentally. The focus is on complex interaction between anisotropic turbulence with inverse energy cascade and Rossby waves. The energy spectrum is highly anisotropic. To diagnose turbulence characterist

Cancellation of drift kinetic effects between thermal and energetic particles on the resistive wall mode stabilization
Autor: Zhirui Wang, S. C. Guo, Yueqiang Liu, X. Y. Xu
Publikováno v: Nuclear Fusion
Drift kinetic stabilization of the resistive wall mode (RWM) is computationally investigated using MHD-kinetic hybrid code MARS-K following the non-perturbative approach (Liu et al 2008 Phys. Plasmas 15 112503), for both reversed field pinch (RFP) an

Context. Among intermediate-mass and massive stars, Be stars are the fastest rotators in the main sequence (MS) and, as such, these stars are a cornerstone to validate models of structure and evolution of rotating stars. Several phenomena, however, i

Turbulence with inverse energy cascade and its transport properties are investigated experimentally in a flow associated with a westward propagating jet. Turbulence and the jet were produced by an electromagnetic force in a rotating tank filled with
