Interaction of Magnetic Fields with a Vortex Tube at Solar Subgranular Scale

2D Numerical Simulation of a Micro Scale Ranque-Hilsch Vortex Tube

  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 f...

Vortex tube formation in solar turbulent convection

Turbulent solar convection is a source of various processes observed as large-scale active phenomena, e.g., coronal mass ejections, formation of self-organized magnetic structures that appear on the surface as sunspots and pores, and other non-linear dynamical structures and phenomena. Modern realistic numerical simulations of solar turbulent phenomena are based on first physical principles and...

Dynamics of the Deep Solar Photosphere at Subgranular Scales

High spatial-resolution spectropolarimetry of small-scale solar magnetic fields

We present a study of the structure and the dynamics of small-scale magnetic elements within solar plage regions. Spectropolarimetric observations with high spatial and spectral resolutions have been obtained for three iron lines with different sensitivities to magnetic field strength and temperature with the Gregory Coudé Telescope at the Observatorio del Teide/Tenerife. The main results are: ...

validation of a revised logical-mathematical intelligence scale and exploring its relationship with english language proficiency

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
