<span>This paper shows electromagnetic field uniformity in an compatibility (EMC) chamber that is used as a test facility for measuring interference and radiated immunity of 6G communication systems. While not defined yet, radio frequency will work the wavelength ranges above 95 GHz. With this reason, designed schroeder-type quadratic residue diffuser GHz to generate uniform EMC studied c...

Abstract To explore the sensitivity sorting of a one-dimensional performance prediction model, high-load centrifugal compressor is studied. Using Latin Hypercube method, influencing factors model are designed. Based on analysis ANOVA, main pressure ratio and efficiency investigated, guidance for optimization proposed. The results show that affecting deviation loss, radial diffuser incidence imp...

Ordinary differential equations(ODEs) with stochastic processes in their vector field, have lots of applications in science and engineering. The main purpose of this article is to investigate the numerical methods for ODEs with Wiener and Compound Poisson processes in more than one dimension. Ordinary differential equations with Ito diffusion which is a solution of an Ito stochastic differentia...

This paper describes curtain airbag gas delivery system development work using CFD analysis. The objective of developing gas delivery system was to achieve uniform inflation and reasonable time to position for oblique pole test with 5 %ile female. CFD analysis has been conducted to design gas delivery system of 3 row curtain airbag. The gas delivery system consists of T-diffuser and flexible ga...

this paper was aimed to report the 3d finite element analysis simulation of laser welding process of ti6al4v 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. the butt-joint welds were made using co2 laser with the maximum power of 2.2 kw in the continuous wave mode. a part of the experimental work was carried out to verify the weld geome...

The effects of the diffuser vane on the performances of the multistage centrifugal pump were investigated experimentally, taking account of the interactions among the diffuser vane, the return vane, and the next stage impeller. It is very important to match well the diffuser vane with the return vane, for improving the hydraulic efficiency of the pump. The efficiency may be more improved by mak...

Preliminary note Uniformity of the radial air jet issuing from the ceiling vortex diffuser with side entry plenum box was investigated experimentally. Two different cases of diffuser plenum box design were used: plenum box with perforated plate and plenum box without perforated plate. Air jet velocities were measured under isothermal conditions circumferentially around a diffuser. It was found ...

Date The final copy of this thesis has been examined by the signatories, and we Find that both the content and the form meet acceptable presentation standards Of scholarly work in the above mentioned discipline. Airflow through an aggressive, constant pressure gradient, flat-bottomed 2D diffuser is simulated with the compressible version of the stabilized, implicit finite element code PHASTA. T...

The effects of using a wind acceleration device (wind lens) with vertical-axis wind turbines in wind tunnel experiments were examined. A wind lens consists of a diffuser and flanges, and this study investigated the optimum parameters of their configuration with regard to the power augmentation of the turbines. The wind lens with a flat-panel-type diffuser demonstrated power augmentation by a fa...
