Abstract: Since 1933, the vortex tube (VT) has been used as a device for cooling, heating, and creating separation process (particles, hydrocarbons, energy, etc.). The VT efficiency is very relevant to the characteristics of the ...

Abstract: The main factors that make longwall mining projects economical are roof control and prediction of roof behavior in roof caving and face advance. Sudden and unexpected roof fall not only endangers the safety of employees ...

Abstract: This paper studies the dynamic behavior of one of the oldest masonry arch bridges of the Iranian railway network, the Veresk bridge, located in the Mazandaran province of Iran. To do so, the writers developed an advanced ...

Abstract: This paper presents an exploration of noncollinear Timoshenko beam structures for attenuating the stress waves generated from impulsive transient loadings. Due to the existence of the noncollinear segments, flexural waves ...

Abstract: The vortex tube (VT) air separator is an invaluable tool which has the ability to separate a highpressure fluid into the cold and hot fluid streams. The hot tube is a main part of the air separator VT which the energy ...

Abstract: Dependence of the yield and fatigue strength of steel bolts with composition in accordance to AISI 1035 manufactured by thread rolling and machining process on dislocation density were investigated. ...

Abstract: This paper describes the wave-propagation behavior of multilayered structures and proposes an optimization procedure for designing layered stress wave attenuators. Two types of stress wave attenuators were investigated, ...

Abstract: In this research, a series of centrifuge modelings, including those with two different superstructures supported by a nonconnected piled raft foundation system (NPRS) in a dry sand bed, was conducted. The superstructures ...
