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 ...
Optimal Control Of Numerical Dissipation In Modified KFVS (m-KFVS) Using Discrete Adjoint Method
(2010-06-04)
The kinetic schemes, also known as Boltzmann schemes are based on the moment-method-strategy, where an upwind scheme is first developed at the Boltzmann level and after taking suitable moments we arrive at an upwind scheme ...
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 ...
Investigation of Heat Transfer Rates Around the Aerodynamic Cavities on a Flat Plate at Hypersonic Mach Numbers
(2018-07-28)
Aerodynamic cavities are common features on hypersonic vehicles which are caused in both large and small scale features like surface defects, pitting, gap in joints etc. In the hypersonic regime, the presence of such ...
Optimal Trajectory Planning for Fixed-Wing Miniature Air Vehicles
(2018-04-02)
Applications such as urban surveillance, search and rescue, agricultural applications, military applications, etc., require miniature air vehicles (MAVs) to fly for a long time. But they have restricted flight duration due ...
Experiments on the Late Stages of Boundary Layer Transition
(2018-03-19)
In canonical boundary layer transition, a uniform laminar flow perturbed by 2-d T-S waves develops downstream into 3-d waves, which eventually break down with turbulent spots appearing. Previous experimental studies have ...
Investigation of Plug Nozzle Flow Field
(2018-03-21)
Plug nozzle, a passive altitude adaptive nozzle, for futuristic SSTO applications, exhibits greater efficiency as compared to conventional nozzles over a wide range of altitudes. The plug nozzle comprises of a primary nozzle ...
Experimental Investigations on Hypersonic Waverider
(2018-02-28)
In the flying field of space transportation domain, the increased efforts involving design and development of hypersonic flight for space missions is on toe to provide the optimum aerothermodynamic design data to satisfy ...
