During the shutdown Baby of a gas turbine, natural convection flows occur inside of the engine casing.These natural convection flows cause the top of the engine casing to cool more slowly than the bottom of the casing.This non-uniform cooling can cause the casing to distort, known as “cat-back” distortion.This distortion leads to reduce
In order to ensure the safety of the tunnel approaching the fault and prevent water inrush disasters, and then take reasonable protective measures, a fault-tunnel-surrounding rock is established by using a three-dimensional (3D) discrete element numerical analysis method, which takes into account the fluid-structure coupling effect.Based on the met

Previous studies have yet to show a consistent effect of severe plastic deformation (SPD) processing on the wear behavior of different metals and Heart Token alloys.To fill this scientific gap, this study investigated the effect of the cyclic extrusion compression (CEC) process, as one of the prominent SPD techniques, on the wear behavior of AA5052
Purposes: In the social sciences, economics is one of the most influential and prestigious disciplines.Mainstream economics typically view economic agent as amoral, entirely self-interested, unrealistic and has damaging effects.In the last few decades, while remaining a powerful discipline, economics has narrowed in scope.Consequently, to reinvigor
