Wavelet Based Spectral Finite Elements For Wave Propagation Analysis In Isotropic, Composite And Nano-Composite Structures
(2009-04-02)
Wave propagation is a common phenomenon in aircraft structures resulting from high velocity transient loadings like bird hit, gust etc. Apart from understanding the behavior of structures under such loading, wave propagation ...
Development And Design Optimization Of Laminated Composite Structures Using Failure Mechanism Based Failure Criterion
(2009-04-27)
In recent years, use of composites is increasing in most fields of engineering such as aerospace, automotive, civil construction, marine, prosthetics, etc., because of its light weight, very high specific strength and ...
Multi-agent Consensus Using Generalized Cyclic Pursuit Strategies
(2009-05-11)
One of the main focus of research on multi-agent systems is that of coordination in a group of agents to solve problems that are beyond the capability of a single agent. Each agent in the multi-agent system has limited ...
Shape Optimization Using A Meshless Flow Solver And Modern Optimization Techniques
(2009-03-17)
The development of a shape optimization solver using the existing Computational Fluid
Dynamics (CFD) codes is taken up as topic of research in this thesis. A shape optimizer
was initially developed based on Genetic ...
Numerical Simulations Of Axisymmetric Near Wakes At High Reynolds Numbers
(2009-03-13)
The flow past the needle of a Pelton turbine injector is an axisymmetric wake embedded in a round jet. The wake does not fully relax to yield a uniform velocity jet due to the short distance
between ...
A Neural Network Approach To Rotorcraft Parameter Estimation
(2009-07-03)
The present work focuses on the system identification method of aerodynamic parameter estimation which is used to calculate the stability and control derivatives required for aircraft flight mechanics. A new rotorcraft ...
Rotationally Invariant Kinetic Upwind Method (KUMARI)
(2009-03-11)
In the quest for a high fidelity numerical scheme for CFD it is necessary to satisfy demands on accuracy, conservation, positivity and upwinding. Recently the requirement of rotational invariance has been added to this ...
On Viscous Flux Discretization Procedures For Finite Volume And Meshless Solvers
(2009-04-29)
This work deals with discretizing viscous fluxes in the context of unstructured data based finite volume and meshless solvers, two competing methodologies for simulating viscous flows past complex industrial geometries. ...
