Development of Optimal Distributed Resource Utilisation Approaches Under Connectivity Constraints for Energy Internet
The global transition to sustainable power generation has driven a rapid increase in Distributed Energy Resources (DERs), especially from renewable sources. When integrated with energy storage, these localised generation ... -
Nonlinear mode theory of shear flow development
The major part of this thesis is concerned with the description of a new technique for analysing the development of shear layers (particularly in free flows). A principal feature of this method is the expansion of the ... -
On the migration of maximum tropical rain fall zone in a simple climate model
The aim of this thesis is to understand the seasonal migration of the maximum precipitation zone in the tropics (ITCZ) using a simple climate model. An attempt is also made to extract at least phenomenological answers to ... -
Effect of convex transverse surface curvature on transition and other properties of incompressible boundary layer.
A study of the incompressible boundary layer with transverse surface curvature has been made with particular reference to transition from laminar to turbulent flow. Calculations based on linearised hydrodynamic stability ... -
Elastic Wave Dispersion Analysis and Mode Shape Investigation of Higher order Beam Theory for Thick Beams
The dynamic behavior of structural components, particularly thick beams, is critical in many engineering applications, including aerospace engineering, civil infrastructure, and mechanical systems. The rigid cross-section ... -
On The Theory of burning of monopropellant droplets
This thesis is concerned with theoretical investigations on some aspects of monopropellant droplet combustion. The burning characteristics have been obtained by solving the governing differential equations which are ... -
Some experimental investigations of the fine scale structure of turbulence
In this thesis some properties of the fine scale structure have been investigated experimentally. The terminology “fine scale structure” means, in the author's opinion, small eddies which are different from energy?containing ... -
Nonequilibrium wake flows
In order to study the memory of the larger eddies in turbulent shear flow, experiments have been conducted on plane turbulent wakes subjected to external pressure gradients. In some of these experiments the pressure gradient ... -
Application of least squares kinetic upwind method to strongly rotating viscous flows
The Least Squares Kinetic Upwind Method (LSKUM) is a node-based method. Ghosh and Deshpande, as well as Ramesh & Deshpande, have demonstrated that LSKUM works on any type of grid—structured, unstructured, Cartesian, Chimera, ... -
Numerical methods for non-homogeneous hyperbolic conservation laws
The numerical simulation of hyperbolic conservation equations has reached a level of maturity with the development of several efficient numerical methods in the past three decades. The same level of success is not present ... -
Some numerical studies on the airflow over mountains
A study of ‘Airflow over Mountains’ is carried out using a two-dimensional, stratified, time-dependent, nonlinear numerical model. Numerical experiments are conducted for high Froude numbers (Fr > 1) and low Froude numbers ... -
Mechanism of reversion in highly accerlerated turbulent boundary layers
This thesis consists of two related parts which are complementary to each other but can also be read independently. The first part is a study of the development of both the mean and fluctuating flow quantities in an initially ... -
some studies on the mean Meriodional circulation droughts
It has been observed that during a break in the Indian southwest monsoon, the middle latitude circulation enters low index regime or Rossby regime. These Rossby waves are found to propagate southwards even up to Indian ... -
Structure of shock waves in a partially ionized gas. Ph.D. Thesis
A unified picture of the structure of steady one-dimensional shock waves in a partially ionized gas in the absence of externally applied electric or magnetic field is presented. The investigation is based on a two-temperature, ... -
Studies on Hydrogen-Enriched Methane Combustion in a Trapped Vortex Combustor
Among conventional fossil fuel–based power generation technologies, gas turbines are among the cleanest and most efficient options. Replacing coal-fired power plants with natural gas–fired open-cycle gas turbines reduces ... -
Effect of particles on nonequilibrium relaxation phenomena in high temperature gas-nozzle flows
This thesis presents an exhaustive study of the effects of solid particles on the relaxation phenomena of various nonequilibrium processes, such as vibrational, dissociation and ionization, of the gas phase at high temperature ... -
Similar solutions in nonequilibrium nozzle flows
The phenomena of thermal and/or chemical nonequilibrium in flowing gases at high temperatures is of fundamental importance in rocket nozzles as well as hypersonic flight simulation facilities. The present state-of-the-art ... -
Bursting phenomenon in turbulent flows
The importance of the phenomenon of bursts in turbulent shear layers has been recognised by fluid dynamicists during the past few years. Kline et al. (1967), Corino & Brodkey (1969), and more recently Grass (1971) noticed ...
