Geochemical and isotopic observations constrain the timing, temperature pressure of Earth's formation. However, to fully interpret these observations, we must know degree mixing equilibration between metal silicates following collisions that formed Earth. Recent fluid dynamical experiments provide initial estimates this mixing, but they entirely neglect inertia planet-building impactors. Here u...
The capture of neutrally buoyant, sub-Kolmogorov particles at the interface deformable drops in turbulent flow and subsequent evolution particle surface distribution are investigated. Direct numerical simulation turbulence, phase-field modelling drop dynamics Lagrangian tracking used. Particle is obtained considering excluded-volume interactions, i.e. by enforcing collisions. Particles initiall...
[1] The Hatteras Front is a persistent mesoscale cross-shelf oriented front off Cape Hatteras, North Carolina. It is the boundary between relatively cool, fresh Mid-Atlantic Bight shelf waters and warmer, saltier shelf waters of the South Atlantic Bight, which both converge along-shelf upon Cape Hatteras year round. The Frontal Interaction Near Cape Hatteras (FINCH) project was conducted in 200...
چکیده دراین پایان نامه خصوصیات حالتهای نهایی چند ذره ای که دربر هم کنشهای الکترون – پوزیترون تولید می شوند رامورد مطالعه قرار می دهیم.شکل رویداد وتوزیع ذرات باردار راارائه می دهیم وسپس اندازه گیریهای خودرا بامدلهای( ترکش+ qcd) مقایسه می کنیم.در این مدلها درمرحله اختلالی از تحول آبشار پارتونی یا عناصر ماتریسی qcd استفاده شده است.در مرحله هادرونی شدن ازترکش string ویا ترکش خوشه ای استفاده می شو...
We model the northern middle radio lobe of Centaurus A (NGC 5128) as a buoyant bubble of plasma deposited by an intermittently active jet. The extent of the rise of the bubble and its morphology imply that the ratio of its density to that of the surrounding ISM is less than 10−2, consistent with our knowledge of extragalactic jets and minimal entrainment into the precursor radio lobe. Using the...
We investigate a nonlocal reaction-diffusion-advection equation which models the growth of a single phytoplankton species in a water column where the species depends solely on light for its metabolism. We study the combined effect of death rate, sinking or buoyant coefficient, water column depth and vertical turbulent diffusion rate on the persistence of a single phytoplankton species. Under a ...
This article deals with the study of the two-dimensional mixed convection magnetohydrodynamic (MHD) boundary layer of stagnation-point flow over a stretching vertical plate in porous medium filled with a nanofluid. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis in the presence of thermal radiation. The skin-friction coefficient, Nusselt number an...
In this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. Bactericidal effect of the plasma jet is also investigated. To that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. Electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...
