TL;DR: This paper is a review of work carried out in the analysis of flow in different turbines employing CFD software, and the merits and demerits of CFD analysis offlow in turbines are mentioned.
Abstract: Computational fluid dynamics (CFD) is a simulation tool, that employs applied mathematics and powerful computer to model fluid flow situations to anticipate the mass, momentum and heat transfer and most favorable design in industrial processes. Turbine is a rotary engine actuated by the impulse or reaction of a current of fluid subject to pressure which is made with a series of curved vanes on a central rotating spindle. CFD at present is the most vital tool to design and analyze different types of turbines. This paper is a review of work carried out in the analysis of flow in different turbines employing CFD software. Literature review of CFD analysis in turbines by various researchers is elucidated. In addition, the merits and demerits of CFD analysis of flow in turbines are mentioned. Future work germane to CFD investigation in turbines is also provided.

TL;DR: In this paper, the analysis of draw component i.e. Vee-Cap used in AC motor and other machines is carried out using ANSYS 16 for the structural analysis of the sheet metal component considered for present study.
Abstract: In this work, analysis of draw component i.e Vee-Cap used in AC motor and other machines is carried out. 3D modeling of the draw component is carried out in Solid Works software. ANSYS 16 is employed for the structural analysis of the sheet metal component considered for present study. Angles 00and 30 at the corner of the draw angle are considered for analysis of the component in order to check the stress distribution at the bottom fillet, which is the most critical part of the component. The displacement of the component is also analyzed to check the plastic strain behavior of the component. From the structural analysis it is clear that the von-mises stress distribution is maximum at 00 and reduced for 30. Whereas, for displacement and plastic strain of the component reduces by increasing the clearance angle from 0 degrees to 3 degrees.

TL;DR: Modeling and analysis of compound tool for Vee-Cap component shows that increasing the tool angle the Stress and Strain are reduced for draw punch, draw tool and component, which gives better performance comparing to other designs.
Abstract: In this paper work is carried out on modeling and analysis of compound tool for Vee-Cap component. Vee-cap (Novibra) part, which is used in AC motor, compressor, milling machines, industrial and marine generators, industrial fans, reserve power plants etc. 3D Modeling of the compound tool component is carried out using Solid Edge V19. Structural analysis is carried out using ANSYS 16 for different angles (0 0 , 3 0 , 4 0 , 6 0 &7 0 ) of the component and the tool revel that increasing the tool angle the Stress and Strain are reduced for draw punch, draw tool and component, which gives better performance comparing to other designs. The induced plastic strain is more at die angle 0 0 clearance i.e. 1.81% which shows that, component is failing due to excessive plastic deformation. The plastic strain for die angle 7 0 is reduced by ~65% and stress reduced by ~64% compared to the other tool angles.
