Glass and ceramics have a fundamental and crucial role in our lives due to their properties and aesthetic decoration. However, they create serious environmental problems, mainly due to their high occupation of landfills and harmful emissions. Both wastes could be utilized to reduce the natural resources' adverse environmental effects and exhaustion...

This technical report presents an evaluation that was developed to clarify alternatives to the Hoover train, after all research reports proved the technical and economic infeasibility of this type of transportation system, due to the cessation of all industrial and technological activities in this direction. After reviewing the scientific research...

This article aims to investigate the aerodynamic noise of the pantograph of the high-speed trains in different operating conditions. CFD technique was used to assess the acoustic noise of the pantograph components. Three-dimensional computational simulations were performed using FLUENT software. Comprehensive analyses of the acoustic pressure and t...

High speed rail systems have significantly developed due to the increased demand on the rail transportation in the recent years. The necessity for enhancing the environmental sustainability of the rail systems imposed many challenges for the researchers to decrease the level of noise generated by the high speed rail systems. This paper aims to inve...

The impact of the in-flow characteristics inside the injection nozzle on atomization has been experimentally and computationally studied. Measurements are carried out using a transparent glass nozzle. Pulsed laser sheet with a synchronized charge-coupled device (CCD) camera and image processing, together with a particle image velocimetry (PIV) setu...

Increasing the axle load for rail freight transportation became necessary to meet the increased demand in goods transportation and the significant progress in manufacturing. The track superstructure represents a crucial part of the structure of railway track systems. The properties of the superstructure components strongly affect the overall track...

The goal of this manuscript is to develop a nonclassical size dependent model to study and analyze the dynamic behaviour of the perforated Reddy nanobeam under moving load including the length scale and microstructure effects, that not considered before. The kinematic assumption of the third order shear deformation beam theory in conjunction with m...

In the present paper, the formation and development of cavitation inside the nozzle of an atomizer with different geometrical characteristics have been studied numerically. Different shapes of inlet nozzles and different nozzle-length-to-diameter ratios have been investigated. The developed model has been built as a three-dimensional (3D) one, wher...
