Evaluation of Air Flow Characteristics of Aerostatic Thrust Porous Bearings: A Numerical Approach by Marcelo Gustavo Coelho Resende, Leandro José da Silva, Cláudio de Castro Pellegrini and Túlio Hallak Panzera* in Crimson Publishers: Structural engineering Aerostatic porous bearings have been investigated in the last decades for precision engineering designs , since these bearings offer zero-friction and high operating speeds, as well as providing a very precise positioning system without external influence. Numerical methods such as CFD (Computational Fluid Dynamics) play an important role in the design and behavior analysis of porous aerostatic bearings, being possible to adjust the geometry and characteristics of the porous restrictor even before its manufacture In the present work, the behavior of the gas at the inlet and outlet of a porous thrust bearing made of cementitious composites is analysed by numerical simulation using CFD method. The results reveal a stable b...

Innovative Method in Recycling Wind Turbine Blades: Mini Review  by Seyed Hossein Mamanpush in  Evolutions in Mechanical Engineering During the past decades many researchers focused on finding a solution for the wind turbine blades that faced end of life but the main challenge for all the previous research was lack of acceptable pathway that was viable economically. Because these blades currently considered as a waste, spending lots of energy and chemical material for them is not an acceptable solution, that is why we suggest an innovative method for solving this problem by considering mechanically recycled wind turbine blades (rWTBs) as a feedstock for making second generation composites. https://crimsonpublishers.com/eme/fulltext/EME.000502.php For more open access journals in Crimson Publishers please click on link: https://crimsonpublishers.com For More Articles on Evolutions in Mechanical Engineering Please click on : https://crimsonpublishers...
