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. ...
Application Of High Frequency Natural Resonances Extracted From Electromagnetic Scattering Response For Discrimination Of Radar Targets With Minor Variations
(Indian Institute of Science, 2005-10-25)
Radars, as the name suggests, were traditionally used for Radio Detection and Ranging. Nevertheless, advances in high resolution electromagnetic simulations, Ultra Wide-Band sources, signal processing and computer technologies ...
Improved Solution Techniques For Trajectory Optimization With Application To A RLV-Demonstrator Mission
(2009-03-12)
Solutions to trajectory optimization problems are carried out by the direct and indirect methods. Under broad heading of these methods, numerous algorithms such as collocation, direct, indirect and multiple shooting methods ...
Kalman Filter Estimation Of Ionospheric TEC And Differential Instrumental Biases Over Low Latitude Using Dual Frequency GPS Observations
(2009-03-13)
The low latitude tropical ionosphere has been investigated by various researchers
using Global Positioning System (GPS). Presently for many civil aviation applications, the ionospheric modeling of the tropical region has ...
Kinetic Flux Vector Splitting Method On Moving Grids (KFMG) For Unsteady Aerodynamics And Aeroelasticity
(Indian Institute of Science, 2007-06-07)
Analysis of unsteady flows is a very challenging topic of research. A decade ago, potential flow equations were used to predict unsteady pressures on oscillating bodies. Recognising the fact that nonlinear aerodynamics is ...
Ultra High Compression For Weather Radar Reflectivity Data
(2007-10-09)
Weather is a major contributing factor in aviation accidents, incidents and delays. Doppler weather radar has emerged as a potent tool to observe weather. Aircraft carry onboard radars but their range and angular resolution ...
Studies On The Combustion And Gasification Of Concentrated Distillery Effluent
(Indian Institute of Science, 2007-04-24)
The need for effective disposal of huge volumes of industrial waste is becoming more challenging due to expected imposition of stringent pollution control regulations in the near future. Thermochemical conversion, particularly ...
2D Compressible Viscous Flow Computations Using Acoustic Flux Vector Splitting (AFVS) Scheme
(Indian Institute of Science, 2007-05-07)
The present work deals with the extension of Acoustic Flux Vector Splitting (AFVS) scheme for the Compressible Viscous flow computations. Accurate viscous flow computations require much finer grids with adequate clustering ...
Transition Zone In Constant Pressure Boundary Layer With Converging Streamlines
(Indian Institute of Science, 2007-04-18)
The laminar-turbulent transition in viscous fluid flows is one of the most intriguing problems in fluid dynamics today. In view of the enormous applications it has in a variety of fields such as aircraft design, turbomachinery, ...
Understanding Context In Designing
(2009-05-25)
Everything around us that is not a simple untouched piece of nature has been designed by someone. Human society has found a great refuge in these designed objects or the artefacts, and thus has adapted vociferously to their ...
