ABSTRACT The partition of decay energy between the kinetic energy of reaction products and their Q-value of formation is obtained in a statistical derivation appropriate to highly excited nuclei, and is shown to be in a constant ratio. We measure the kinetic energy fraction, R = ΣEkin/(ΣEkin + ΣQ0), over a wide range of excitation energy for welldefined systems formed in the Cl+C reaction at 35...
Kolmogorov second-order structure functions are used to quantify and compare the small-scale information contained in near-surface ocean wind products derived from measurements by ASCAT on MetOp-A and SeaWinds on QuikSCAT. Two ASCAT and three SeaWinds products are compared in nine regions (classified as rainy or dry) in the tropical Pacific between 10 S and 10 N and 140 and 260 E for the period...
It has been tried to prove: 1. The photons possess rest mass; 2. Since the electrons possess spin motion, the photons emitted from the orbiting electrons too should possess spin motion and their (photons) velocity should depend upon frequency of their spin motion ( ph w ); 3. The velocity of photons of infrared, visible, ultraviolet and higher frequency regions should also depend upon their ph ...
High-resolution global ocean models forced by atmospheric fields and tides are beginning to display realistic internal gravity wave spectra, especially as model resolution increases. This paper examines internal waves in global simulations with 0.08° and 0.04° (~8 and 4 km) horizontal resolutions, respectively. Frequency spectra of internal wave horizontal kinetic energy in the North Pacific li...
Influence of insertion of holes in the middle of obstacles on the flow around a surface-mounted cube
The aim of our study is to analyze the impact of insertion holes in the middle of obstacles on the flow around a surface-mounted cube, In order to do this; we studied four configurations of obstacles in a channel with a Reynods number based on obstacle height ReH = 40000. The hexahedral structured meshes were used to solve the fluid dynamics equations .The finite volume method are employed to s...
this research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (pvb) based on weight loss analysis and non-isothermal approaches. the weight loss by the un-irradiated pvb upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...
The effect of forced near-inertial motion on the kinetic energy budget of a turbulent, geostrophic background flow is examined using a primitive equation ocean circulation model. Balanced and unbalanced parts of the flow are taken to be equivalent to lowand high-passed filtered versions of the model fields, and the Reynolds stresses associated with the high-passed, predominantly near-inertial p...
Zonal wind stress over the Southern Ocean may be responsible for a significant fraction of the meridional overturning associated with North Atlantic Deep Water. Numerical experiments by Tsujino and Suginohara imply that the zonal periodicity of the Southern Ocean is not necessary for midlatitude westerly winds to drive strong remote meridional overturning. Here, idealized numerical experiments ...
1. Motivation and objectives The purpose of this research is to construct accurate finite difference schemes for incompressible unsteady flow simulations such as LES (large-eddy simulation) or DNS (direct numerical simulation). Experience has shown that kinetic energy conservation of the convective terms is required for stable incompressible unsteady flow simulations. Arakawa (1966) showed that...
