Heat Transfer and Visualization Studies in the Evaporator of a Flat Loop Heat pipe
Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ...
Studies on Characteristics of Stabilized Soil Compacts for Structural Applications
Earth based construction materials are identified as green and low carbon materials. There are sustained R&D efforts in developing stabilised earth products for buildings and other structural applications. The thesis ...
Design of Planar Supersonic Wind Tunnel Nozzle
This thesis revisits the design of a planar supersonic nozzle for a supersonic wind tunnel using
the method of characteristics (MOC) and Computational Fluid Dynamics (CFD). While design
of a converging-diverging (CD) ...
Efficacy of Solar irradiance, Methane and Black carbon aerosols
In climate science literature, the concept of radiative forcing is used to infer the equilibrium temperature change that would occur as a result of changes in the forcing agents such as greenhouse gases and aerosols. ...
Innovative Optimal Guidance of Spacecrafts for Soft-Landing on Atmosphere-less Celestial Bodies
Nonlinear trajectory optimization based optimal guidance schemes are presented in this thesis for soft-landing of spacecrafts on atmosphere-less celestial bodies. First, a pseudo-spectral philosophy based multi-phase ...
Parameter Estimation to Determine the Groundwater Flow and Seawater Intrusion in a Coastal Aquifer of Karnataka, India
Seawater Intrusion (SWI) into the fresh groundwater aquifers is one of the major hydrological problems in coastal regions. This global issue is aggravated by increasing demands for fresh groundwater due to on-going ...
Improvement of High Temperature Oxidation Behavior of ‘w’ Free Y strengthened Co-based Superalloys through Alloying Addition
The discovery of coherent g-g’ microstructure in Co-Al-W and Co-Al-Mo-Nb/Ta systems represents new possibilities for turbine engines materials. Their chemical and mechanical properties are similar to commercially successful ...
Lattice Boltzmann Relaxation Schemes for High Speed Flows
The lattice Boltzmann method (LBM) has emerged as a highly efficient model
for the simulation of incompressible
flows in the last few decades. Its extension to
compressible
flows is hindered by the fact that the ...
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 ...
Analysis of the Flow of Granular Materials through a Screw Conveyor
Screw conveyors are widely employed in industry for the bulk transport of particulate materials. Several studies have attempted to correlate the discharge rate with the rotation speed of the screw via experiments and ...
