Experiments on the Late Stages of Boundary Layer Transition
(2018-03-19)
In canonical boundary layer transition, a uniform laminar flow perturbed by 2-d T-S waves develops downstream into 3-d waves, which eventually break down with turbulent spots appearing. Previous experimental studies have ...
Influence of Chemical Coating on Droplet Impact Dynamics
(2018-03-09)
Dynamic behavior of impacting water drops on superhydrophobic solid surfaces provides important details on the stability/durability of such solid surfaces. Multi-scale surface roughness combined with a layer of low energy ...
Linear Stability Models for Reacting Mixing Layers
(2018-03-12)
We develop a physics-based reduced-order model of the aero-acoustic sound sources in reacting mixing layers as a method for fast and accurate predictions of the radiated sound. Instabilities in low-speed mixing layers are ...
Lattice Boltzmann Relaxation Scheme for Compressible Flows
(2018-03-09)
Lattice Boltzmann Method has been quite successful for incompressible
flows. Its extension for compressible (especially supersonic and hypersonic)
flows has attracted lot of attention in recent time. There have been ...
Inverse Problems in Free Vibration Analysis of Rotating and Non-Rotating Beams and its Application to Random Eigenvalue Characterization
(2018-02-19)
Rotating and non-rotating beams are widely used to model important engineering struc-tures. Hence, the vibration analyses of these beams are an important problem from a structural dynamics point of view. Depending on the ...
Studies on the Effects of Carbon Nanotubes on Mechanical Properties of Bisphenol E Cyanate Ester/Epoxy Based Resin Systems and CFRP Composites
(2018-02-28)
The search and research for high performance materials for aerospace applications is a continuous evolving process. Among several fibre reinforced polymers, carbon fibre reinforced polymer (CFRP) is well known for its high ...
Design and Development of Piezoelectric Stack Actuated Trailing Edge Flap for Helicopter Vibration Reduction
(2018-01-09)
This research investigates on-blade partial span active plain trailing edge flaps (TEFs)with an aim to alleviate the helicopter vibrations. Among all the available smart materials, piezoelectric stack actuator(PEA)has shown ...
Delamination Modeling and Detection in Composite Structures
(2017-12-12)
Composite laminated structures are prone to delamination. Rotorcraft flexbeams, apart from many other aerospace primary load carrying members are made up of composite laminated structures. A delaminated primary load carrying ...
A Study of the Characteristics of Gas-On-Liquid Impinging Injectors
(2018-02-18)
The work presented here pertains to investigations on gas-on-liquid type of impinging injectors with a generic approach with prospective applications in several areas, and at places with particular emphasis on cryogenic ...
Investigation of Plug Nozzle Flow Field
(2018-03-21)
Plug nozzle, a passive altitude adaptive nozzle, for futuristic SSTO applications, exhibits greater efficiency as compared to conventional nozzles over a wide range of altitudes. The plug nozzle comprises of a primary nozzle ...
