A Synergetic Micromechanics Model For Fiber Reinforced Composites
(2014-09-08)
Composite materials show heterogeneity at different length scales. hence concurrent multiscale analysis is the only reliable method to analyze them. But unfortunately there is no concurrent multi-scale strategy that is ...
Wave Propagation In Hyperelastic Waveguides
(2014-06-20)
The analysis of wave propagation in hyperelastic waveguides has significant applications in various branches of engineering like Non-Destructive Testing and Evaluation, impact analysis, material characterization and damage ...
Modeling And Computation Of Turbulent Nonreacting And Reacting Sprays
(2014-09-05)
Numerical modeling of several turbulent nonreacting and reacting spray jets is carried out using a fully stochastic separated flow (FSSF) approach. As is widely used, the carrier-phase is considered in an Eulerian framework, ...
Packed Bed Gasification-Combustion In Biomass Based Domestic Stoves And Combustion Systems
(2014-07-04)
This thesis constitutes fundamental experimental and computational investigations on gasification and combustion in a packed bed of biomass. Packed bed gasification-combustion in counter-current mode is used in two ...
Evolutionary Optimization For Vibration Analysis And Control
(2014-03-03)
Problems in the control and identification of structural dynamic systems can lead to multimodal optimization problems, which are difficult to solve using classical gradient based methods. In this work, optimization problems ...
Role Of Hydrogen Injection Temperature On The Combustion Instability Of Cryogenic Rocket Engine
(2014-04-16)
Physical mechanism for high frequency instability in cryogenic engines at low hydrogen injection temperature has been a subject of debate for long time. Experimental and early developmental studies revealed no instabilities ...
Experimental Measurement Of Flame Response To Acoustic Oscillations
(2014-06-20)
Acoustic instabilities in a combustion chamber arise due to the coupling of acoustic pressure with in-phase heat-release, and are characterized by large amplitude oscillations of one or more natural modes of combustor. ...
Modelling And Analysis Of Fish Inspired Ionic Polymer Metal Composite Flapping Fins
(2014-03-03)
Ionic polymer metal composites (IPMC) are a new class of smart materials that have attractive characteristics such as muscle like softness, low voltage and power consumption, and good performance in aqueous environments. ...
Parametric Analysis Of A Free Piston Stirling Engine For Spacecraft Power Applications With A Radioisotope Heat Source
(2014-07-11)
Stirling engines are promising candidates for applications where air breathing engines cannot be used. Self contained engines capable of operating independently of the environment are required to convert thermal energy ...
Assesment Of Air Quality And Anthropogenic Aerosol Fraction Over India Using Observations And Model
(2014-12-11)
Air quality degradation is emerging to be an issue of major concern in India. Recent investigations have shown that anthropogenic aerosols have significant impact on climate as well as on health. In fourth assessment report ...
