Review of Shock-Boundary Layer Controlled Interactions Studies in High Speed Intakes
Abstract: Normal 0 false false false EN-US X-NONE X-NONE The present work review about the studies conducted by various researchers on shock-boundary layer interactions and their control in high speed intakes. The shock-boundary layer interactions have been a topic of immense interest among the researchers for past many decades due to their associated aerodynamic and aerothermodynamic phenomena. The sudden retardation at the shock impact point promotes, either the boundary layer thickening …

Superiority of Tabs with Corrugations on Jet Mixing
Abstract: Normal 0 false false false EN-US X-NONE X-NONE The jet mixing promoting effectiveness of two identical rectangular tabs of blockage 2.5% (each), placed diametrically opposite at the exit of a Mach 1.65 axi-symmetric nozzle, is experimentally investigated. The efficacy of the tab with and without corrugations is studied at varied levels of expansions present at the nozzle exit. To quantify the tab performance the total pressure distribution along and across …

Bending Analysis of Sandwich Beams According to Refined Trigonometric Beam Theory
Abstract: An equivalent single layer trigonometric shear deformation theory is presented for flexure of sandwich beams. The axial displacement field uses trigonometric function in terms of thickness coordinate to include the effect of transverse shear deformation. The transverse displacement is assumed to be a function of longitudinal direction. Normal and shear strains corresponding to assumed displacement field of the present theory are obtained within the framework of linear theory of elasticity. …
