Analytical Comparison of a Gas Turbine Blade Cooling Using Wet and Dry Air
Abstract: Air cooling is widely used technique to shield the turbine aerofoils against hot flue gases. The cooling of a gas turbine blade using wet air and dry air as a coolant is analytically investigated. The investigation is carried out considering effect of rotation for inward and outward flow of coolant. Wet air cooling performance is compared with dry air cooling. It has been observed that wet air provides better cooling …

Experimental Determination of Tire Stiffness using Nitrogen
Abstract: Vehicle stability generally depends on the tire forces and torque at wheel. Forces and reactions generated at tire play major role in the control of vehicle. On application of torque to the wheel, due to contact friction between road, tire pushes on the ground and moves forward and backward. Tire also supports the load of vehicle and deforms under load for the flexibility and damping. The stiffness of fluid in …

Effect of Different Parameters on Energy Loss Coefficient of Square Edged Orifice Plate
Abstract: Orifice meter is a differential pressure type flow measuring device in which energy loss is a major problem. The energy loss coefficient is an important indicator of energy dissipation. In this paper, different parameters like contraction ratio, orifice plate thickness and Reynolds number were analyzed by numerical simulations using Ansys CFX 15.0 software for their effects on energy dissipation. Results of simulations revealed that, Reynolds number has negligible effect on …

Finite Element Analysis of Thick Beams using Lagrange-9 Element and ADINA
Abstract: There has been a lot of research in the field of thick beam analysis. The classical beam theory was the first beam theory but it neglected the effects of shear deformation and this induce the need for further research to develop the beam theory to be helpful in thick beams where the shear deformation is paramount. In this research work, the trigonometric shear deformation theory for thick beam, which includes …
