Experimental studies on Soot and Particulate reduction in Heavy Fuel Oil Combustion
Heavy fuel oil (HFO) is extensively used in industrial burners and marine engines. HFO droplet combustion gives rise to carbon particulates generated by pyrolysis, which are called cenospheres. There is a current hypothesis ...
Advanced Guidance Laws for Field-of-View and Impact Angle Constrained Engagements
This thesis deals with the development of guidance laws for interceptors with seeker field-of-view
(FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of-
view and impact angle constrained ...
Investigations on Impinging Shock Wave and Boundary Layer Interactions in Hypersonic Flow
Shock boundary layer interactions (SBLIs) rank among the most fundamental problems in high-speed aerodynamics and are a primary concern in hypersonic flows. Shocks at hypersonic speeds are typically strong enough to separate ...
Adaptive Filtering for Large Eddy Simulation of Flows with Shocks and its Application to Launch Pad Deflectors
During lift-off of launch vehicles jets from nozzles impinge on a wedge deflector which
directs the jet away from the rocket along passages. As a high Reynolds number turbulent
flow the whole region has a broad spectrum ...
Interaction behavior and droplet characteristics of multi-injector sprays
The injector faceplate of a liquid propellant rocket engine is comprised of numerous single-element atomizers to inject propellants into the engine thrust chamber. The sprays from these single-element atomizers interact ...
Design of Curved Aggressive Annular Diffusers
For economical air transportation, aero engines with lower specific fuel consumption, lower emissions and lower noise levels are required. To this end, the use of turbofan engine with high bypass ratio is an option. With ...
Synthesis and testing of eco-friendly, non-toxic cutting fluid emulsions
The evolutions in the development of metal working fluid (MWF) from petroleum based products have brought remarkable changes to the present growing machining industry. The established MWF/Cutting fluids have reduced the ...
Subsonic, turbulent, round and plane, twin jets
Multiple jets appear in many engineering applications such as engines of launch vehicles
and aircraft, fuel injectors and other mixing devices. Twin jets are models to understand
the differences from single jets that can ...
Non-linear Vibration of Beam Immersed in Fluid
In space launch vehicles with liquid propulsion system, various sub-systems like gas bottles, anti-slosh baffles and fluid lines are placed inside the propellant tanks which become partially filled over time during flight. ...
Vapor Mediated Interaction in Droplets
Controlling internal flow in evaporating sessile droplets is desirable across applications ranging from lab-on-chip medical diagnostics, DNA profiling to surface patterning. Diffusion-limited evaporation in droplets exhibits ...
