Cerium Oxide Based Active Catalyst for Green Hydroxylammonium Nitrate (HAN) Fueled Monopropellant Thruster
Monopropellants are widely used for propulsion and gas generation applications. The current state of art monopropellant systems are based on hydrazine propellants. While hydrazine has a strong heritage as a versatile ... -
Characterization and Control of Boundary Layer Transition Caused by Distributed Surface Roughness
Distributed roughness occurs over a variety of aerodynamic surfaces such as wind-/gas-turbine blades and aircraft wings in the form of dust, insect strikes, fouling or icing. The disturbances introduced by the roughness ... -
Characterization of a large scale hypersonic shock tunnel and investigation of the effect of roughness on a large cone boundary layer flow
High speed flight is ridden with engineering challenges, some of which have been studied for decades with only minor improvements. Boundary layer transition to turbulence in highMach number flow is one such topic, which, ... -
Characterization of Cure Residual Strain in CFRPs
Fiber reinforced plastic (FRP) structures are widely used compared to metallic structures due to their superior mechanical properties and lightweight. However, anisotropy and heterogeneity inherent to FRPs cause a multitude ... -
Characterization of high enthalpy flows in the IISc free-piston driven shock tunnel using Two-Colour Ratio Pyrometry
High temperature and its associated effects set the hypersonic flow regime apart from other class of flows. Viscous dissipation raises the internal energy of the high-kinetic-energy gas as it slows down in the boundary ... -
A Class of Vector Fields for Path Following Guidance
With rapidly evolving application scenarios, Unmanned Aerial Vehicles (UAVs) are often desired to autonomously follow predefined paths. Prospective path following guidance methods should cater to the dynamic capability of ... -
Closed-form Solutions For Rotating And Non-rotating Beams : An Inverse Problem Approach
(2012-12-04)Rotating Euler-Bernoulli beams and non-homogeneous Timoshenko beams are widely used to model important engineering structures. Hence the vibration analyses of these beams are an important problem from a structural dynamics ... -
Co-operative Destabilization of a Flat Plate Boundary Layer by a Free Stream Convecting Vortex and Wall Suction/Blowing
The stability of wall bounded shear layer at subcritical Reynolds number disturbed by a freestream convecting vortex and unsteady suction/blowing at the wall was studied. A counterclockwise line vortex was convected parallel ... -
