A sweep process of a wing is very useful technique to enhance an aircraft performance especially the which fly in sonic and supersonic areas. In this research, influence swept on aerodynamic characteristics generation at speeds has been studied analyzed using CFD technique. The 3D model presented paper NACA 2412 profile. governing equations such as continuity, Energy Equation, Reynolds Averagin...

This paper describes a novel experiment on nitroxide radical spin labels using a multiarm EPR W-band bridge with a loop-gap resonator (LGR). We demonstrate EPR spectroscopy of spin labels by linear sweep of the microwave frequency across the spectrum. The high bandwidth of the LGR, about 1 GHz between 3 dB points of the microwave resonance, makes this new experiment possible. A frequency-tunabl...

The basic problem which this paper addresses is the following: given an arbitrary three-dimensional object, which moves along an arbitrary path (possibly rotating as it does so), to compute the volume swept out by the solid object as it moves, or in other words, to find the new solid volume which represents all of the points in space which the object has occupied at some time during the motion....

PURPOSE Define criteria for iris-related parameters in an adult open angle population as measured with swept source Fourier domain anterior segment optical coherence tomography (ASOCT). METHODS Ninety-eight eyes of 98 participants with open angles were included and stratified into 5 age groups (18-35, 36-45, 46-55, 56-65, and 66-79 years). ASOCT scans with 3D mode angle analysis were taken wi...

We carry out high resolution simulations of the inner regions of a wide angle wind driven bipolar outflow using an Adaptive Mesh Refinement code. Our code follows H-He gas with molecular, atomic and ionic components and the associated time dependent molecular chemistry and ionization dynamics with radiative cooling. Our simulations explore the nature of the outflow when a spherical wind expands...

Received ; accepted – 2 – ABSTRACT Beaming of relativistic ejecta in GRBs has been postulated by many authors in order to reduce the total GRB energy, thus it is very important to look for the observational evidence of beaming. Rhoads (1999) has pointed out that the dynamics of the blast wave, which is formed when the beamed ejecta sweeping the external medium, will be significantly modified by...

The effect of the swirl clocking on three-dimensional nozzle guide vane (NGV) is investigated using computational fluid dynamics. research reports loss characteristics leaned and swept NGVs influence clocking. are built by stacking same 2D profile along different linear axes, characterized angles with respect to normal or radial direction: ε = −12° ~ +12° for γ −5° +10° airfoils. A total 40 mod...
