چکیده
Numerical modeling of propagation and absorption fast waves (helicons) with frequency 200MHz in 2D inhomogeneous plasma the spherical tokamak Globus-M2 was carried out full-wave code. Toroidal effects, poloidal magnetic field actual shape flux surfaces were taken into account. The full wave electric RF power profiles computed by solving equation electron Landau damping term. demonstrated a fairly high efficiency helicons bulk within wide range experimental parameters. propagate to inner regions column are mainly absorbed there; less than 20% energy returns back periphery. Keywords: temperature plasma, nuclear fusion, tokamak, waves, helicons, equation,

15 صفحه اولA Potential Method for Body and Surface Wave Propagation in Transversely Isotropic Half- and Full-Spaces
The problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. Using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...
متن کاملPlasma-Wall Interaction in the Open Divertor of Globus-M Spherical Tokamak
Composition, morphology and structure of the deposited (mixed) surface layers after preliminary carboboronization procedure (B/C:H layers deposition) and subsequent plasma-wall interaction in the different regions of Globus-M spherical tokamak have been analyzed. Globus-M to the best of our knowledge is unique in that its first wall is almost completely covered by RGTi protection tiles: current...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اول2D NUMERICAL MODELING OF WAVE TRANSFORMATION ON SOFT MUDDY BEDS
The present paper offers a numerical model which can be applied for the simulation of wave height distribution on a 2-D horizontal soft mud layer. The model is based on mild slope equations and it includes combined wave refraction, diffraction, reflection and breaking. The high energy dissipation of wave height due to the presence of fluid mud layer has also been simulated. Wave height attenuat...
