The investigation showed that the effect of particle size on the flow properties of pulverized coal is diversity and rheological test results can reflect flow properties of pulverized coal to some extent. For reproduction of material from PPS: The grain size was 0.
The data used are based on VERA core physics benchmark problem. The assembly is specified without spacer grid and without Pyrex absorbers. Three samples were tested for each flow property measurement and the mean values of the flow functions, bulk densities and friction functions were plotted.
The infinite and radial power distributions are calculated for the two models to study the effects from spacer grids. The intermediate grids are located in the active fuel region and are made of Zircaloy-4 to limit neutron absorption.
Next generation evaluated nuclear data library for nuclear science and technology", Nuclear Data Sheets Most of the geometrical and material data is based on actual fuel and plant data from the initial core loading of Watts Bar Nuclear1 reactor WBN1.
In the third and fourth sections, we use HiPPSTR to analyze droplet motion in isotropic turbulence, which we take to be representative of adiabatic cloud cores. HiPPSTR uses efficient parallelization strategies, timeintegration techniques, and interpolation methods to enable massively parallel simulations of three-dimensional, particle-laden turbulence.
For all cases 2D and 3D dimension the standard division and the estimated relative error associated with the value of the maximum difference between the reference and the present results is reliable as stated in MCNP manual.
Density changes can be measured directly and changes in other properties can be inferred. The available rod data for fuel rod arrangement is presented in table 2.
In the 3D model the effective multiplication factors and axial power distribution are calculated with and without Pyrex to study the effect of using Pyrex burnable absorber.
The addition of amorphous boron in the milling process and the increase of the milling time were used to improve the formation of the amorphous phase.
Radial 17x17 Fuel Rod Assembly Figure 2. Fuel Assembly Specification Fuel Rod Geometry It contains UO2 fuel stack within Zircaloy-4 cladding with an upper gas plenum, plenum spring, and upper and lower end plugs.
The PV module with a higher temperature difference experiences a lower dust density because of the effect of the thermophoresis force arising from the temperature gradient between the module surface and its surrounding air. Sustainability8, Such trends have been attributed, in part, to nanoparticle deposition on the heater surface.
One of the remaining questions in modelling radiological consequence of a RDD terrorist event is how should the particle size effect be treated.
Previous article in issue. This paper describes a theoretical investigation into (i) the response of a spherical particle to a one-dimensional fluid flow, (ii) the motion of a spherical particle in a the blades whereas in flow through a filter the opposite effect is needed.
In either. The effect of medium temperature upon characteristic of stimulated Brillouin scattering (SBS) and SBS optical limiting is investigated. The physical mechanism behind is analyzed theoretically and experimentally verified in Continuum's Nd: YAG Q-switched.
The solid particle erosion rates are defined as [33, 34] where is a function of particle diameter, is a function of impact angle, is the angle between the particle trajectory and wall, is the relative velocity among particles, is a function of relative velocity among particles, and is the cell face area at the wall.
Journal of Electroanalytical Chemistry – Effect of particle size on the electrocatalysis by carbon-supported Pt electrocatalysts: an in situ XAS investigation 1 Sanjeev Mukerjee, James McBreen).
The purpose of this study is to examine how aluminum powder particle size impacts the detonation velocity, metal accelerating ability, and airblast pressure of small scale, pressed RDX based charges.
This paper reports an experimental investigation of the dust particle deposition process on solar photovoltaic (PV) modules with different surface temperatures by a heating plate to illustrate the effect of the temperature difference (thermophoresis) between the module surface and the surrounding air on the dust accumulation process under different operating temperatures.Investigation of the effect of particle
