Numerical Simulation of Flow Field, Fountain Flow and Associated Noise in Supersonic Impinging Twin Jet using Large Eddy Simulation
Abstract: A three-dimensional flow field is produced by a supersonic twin-jet impingement. It is studied using the turbulence model Large Eddy Simulation (LES). The numerical model consists of two parallel jets of diameter 3D apart, which are issued from a plane which is at a distance H = 2D, 3D, 4D above the ground. The Nozzle Pressure Ratio (NPR) is kept at 3.7 for all the flow conditions. The study is …

Conceptual Design and Validation of Working of the Wing Morphing Mechanism Using Bellows
Abstract: The research on creating a smooth seamless wing which can literally morph its shape in mid-flight like birds has been in progress for many years. Such a wing will greatly enhance the flying capabilities of a normal aircraft. The wing can be morphed at different speeds to increase greater fuel efficiency. Our new design tends to create such a design without interfering with structural integrity of the wing. Keywords: Morphing …

Displacements in Thick Beams Using Refined Shear Deformation Theory
Abstract: Normal 0 false false false EN-US X-NONE X-NONE A trigonometric shear deformation theory for displacement of thick beams, by considering the transverse shear deformation effects, is presented. Variables in the present theory are same as that of in the first order shear deformation theory. The sinusoidal function is used in displacement field in terms of thickness coordinate to represent the shear deformation effects. Governing differential equations and various boundary conditions …
