Development Of A New Finite-Volume Lattice Boltzmann Formulation And Studies On Benchmark Flows
This thesis is concerned with the new formulation of a finite-volume lattice Boltzmann equation method and its implementation on unstructured meshes. The finite-volume discretization with a cell-centered tessellation is ...
Dynamics And Stability Of A Launch Vehicle
Stability is an important criterion in the design and performance of launch vehicles. Present day launch vehicles have become more and more flexible due to the constraints of weight reduction, necessarily imposed for ...
Large Eddy Simulation of Multiphase Flows
Multiphase ﬂows are a common phenomenon. Rains, sediment transport in rivers, snow and dust storms, mud slides and avalanches are examples of multiphase ﬂows occurring in nature. Blood ﬂow is an example of multiphase ﬂow ...
Active Vibration Control Synthesis Using Viscoelastic Damping Phenomena
In this thesis, a new method is followed to design an active control system which imparts viscoelastic phenomenological damping in an elastic structure. Properties of a hypothetical viscoelastic system are used to design ...
Time Scale Separated Nonlinear Partial Integrated Guidance And Control Of Endo-Atmospheric Interceptors
To address the concern of classical guidance and control designs (where guidance and control loops are designed separately in an “outer loop – inner loop” structure), integrated guidance and control (IGC) ideas have been ...
Time-Optimal Guidance for Impact Angle Constrained Interception of Moving Targets
Various unmanned missions deploy vehicles such as missiles, torpedoes, ground robots, and unmanned aerial vehicles. Guidance strategies for these vehicles aim to intercept a target point and satisfy additional objectives ...
