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 ... -
Determination Of Isopectral Rotating And Non-Rotating Beams
(2016-04-27)In this work, rotating beams which are isospectral to non-rotating beams are studied. A rotating beam is isospectral to a non-rotating beam if both the beams have the same spectral properties i.e; both the beams have the ... -
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 ... -
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. ... -
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 ... -
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. ... -
Optimal Guidance Of Aerospace Vehicles Using Generalized MPSP With Advanced Control Of Supersonic Air-Breathing Engines
(2016-07-11)A new suboptimal guidance law design approach for aerospace vehicles is proposed in this thesis, followed by an advanced control design for supersonic air-breathing engines. The guidance law is designed using the newly ... -
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 ... -
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 ... -
A Residual Based h-Adaptive Strategy Employing A Zero Mean Polynomial Reconstruction
(2016-04-18)This thesis deals with the development of a new adaptive algorithm for three-dimensional fluid flows based on a residual error estimator. The residual, known as the R –parameter has been successfully extended to three ... -
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 ... -
Structural Modeling And Analysis Of Insect Scale Flapping Wing
(2013-06-04)Micro Air Vehicles (MAVs) are defined as a class of vehicles with their larger dimension not exceeding 15 cm and weighing 100 gm. The three main approaches for providing lift for such vehicles are through fixed, rotating ... -
Studies On Shock Wave Attenuation In Liquids
(2013-06-11)The attenuation mechanism of shock waves of arbitrary strength propagating in air has been reasonably well understood. On the other hand, very little is known about the precise mechanism of shock wave attenuation and energy ... -
Wave Propagation in Healthy and Defective Composite Structures under Deterministic and Non-Deterministic Framework
(2018-03-08)Composite structures provide opportunities for weight reduction, material tailoring and integrating control surfaces with embedded transducers, which are not possible in conventional metallic structures. As a result there ... -
