We report our simulations on the profile of the electric field in semi insulating CdTe and CdZnTe with Au contacts under radiation flux. The type of the space charge and electric field distribution in the Au/CdTe/Au structure is at high fluxes result of a combined influence of charge formed due to band bending at the…
During service, gas turbine blades and vanes are ex posed to thermal stresses and to oxidation and hot corrosion from the hot combustion gas. Therefore, the coating process is a good alternative to protect the turbine. In the pre sent work is studied the benefits of the application of two coating layers to enhance the…
This paper describes the numerical simulation of the igni tion period structural response of a prototype composite solid rocket motor nozzle to a combination of pressure and thermal loading , using a multiphysics finite element approach . Loading conditions characterized by high spatial and t emporal resolution were g…
A new approach to modelling the behaviour of simple fluids is presented. Starting from the usual expression of the partition function of N molecules, a Fourier transformation is performed. It is argued that the N(N-1)/2 dynamical variables kpq in the reciprocal space featuring the link between 2 molecules p and q can…
Cadmium Zinc Telluride (CZT) is attracting increasing interest with its promise as a room-temperature nuclear-radiation-detector material. The distribution of the electric field in CZT detectors substantially affects their detection performance. At Brookhaven National Laboratory (BNL), we employed a synchrotron X-Ray…
All papers published in this volume of Journal of Physics: Conference Series have been peer reviewed through processes administered by the proceedings Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing.
To design the rocket motor, thrust and burning rate of propellant are important factors. The large range of burning rate makes the design criteria increase. The range of burning rate is expanded with catalyst or changing the size of oxidizers, however the range of burning rate of ammonium perchlorate composite propell…
We present results from Monte Carlo simulations of a three dimensional fermionic field theory which can be derived from a model of graphene in which electrons interact via a screened Coulomb potential. For our simulations we employ lattice gauge theory methods used in elementary particle physics. We show that the theo…
The high temperature heterogeneous oxidation of bulk tungsten (W) was studied using thermogravimetric analysis over a range of flow reactor temperatures and steam (H2O) pressures, supporting previous work involving O2, CO2, and CO reactions with W. Isothermal reaction rates were determined at temperatures ranging from…
The research reported here focuses on the surface topography of a field-emission cathode for use in Electric Propulsion (EP) that has the potential for very long lifetime and the added ability to be re-generated when the emitter sites become damaged. The cathode was formed by the application of an ion-extracting elect…
The purpose of this paper is to give a detailed description of the design, activation, and operation of the J2-X Subscale Simulator (JSS) installed in Cell 1 of the E3 test facility at Stennis Space Center, MS (SSC). The primary purpose of the JSS is to simulate the installation of the J2-X engine in the A3 Subscale R…
The purpose of this paper is to give an overview of the general design and operation of the A3 Subscale test facility. The goal is to provide the reader with a general understanding of what the major facility systems are, where they are located, and how they are used to meet the objectives supporting the design of the…
While preserving many of the unusual features of single-layer graphene, few-layer graphene (FLG) provides a richness and flexibility of electronic structure that render this set of materials of great interest for both fundamental studies and applications. Essential for progress, however, is an understanding of the evo…
�ew metalbased reactive materials are being develo ped aimed to replace aluminum as a fuel additive in propellants, explosives, and pyrotechnics. Recently, potential benefits of mechanically alloyed Alrich AlTi powders were dis cussed in the literature; however, preparation of fine powders of such alloys could not be…
There is interest in replacing energetically inert structural components with reactive structures capable of highly exothermic reactions. Consolidated reactive materials are also desired for other applications, including reactive fragments, high density additives to explosives, insensitive pyrotechnic components, etc.…
