Review of internal cooling augmentation using baffles

  Heat transfer augmentation techniques refer to different methods used to increase rate of heat transfer without affecting much overall performance of the system. These techniques are used in heat exchangers. Like ribs, jet impingement and other passive heat transfer enhancement methods, insertion of baffle in a cooling system has been used for various types of industrial applications such as internal cooling...

Static analysis of mono leaf spring with different composite materials

  In the present scenario, composites are widely used in most of the industries in place of steel, due to low weight to strength ratio. In automobile industry, one can think of replacing parts with composites. The aim of this paper is to suggest the best composite material for design and fabrication of complete mono composite leaf spring. A single leaf with variable thickness and variable width for constant...

Exergy analysis of high-performance cycles for gas turbine with air-bottoming

  Exergy is described as a measure for identifying and explaining the benefits of technologies. Therefore in this research the performance of water and steam injection in the gas turbine with air bottoming cycle (ABC) is evaluated based on an exergy analysis and thermodynamic laws. In this study, we suggest four efficient cycles...
