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 ... -
On the nature of transonic buffet in a finite span wing
Transonic buffet, or self-sustained shock oscillations caused by shock boundary layer interactions, creates lift and drag fluctuation on the wing of an aircraft. This aerodynamic instability limits the flight envelope of ... -
On The Reduction Of Drag Of a Sphere By Natural Ventilation
(Indian Institute of Science, 2005-07-08)The problem of bluff body flows and the drag associated with them has been the subject of numerous investigations in the literature. In the two-dimensional case, the flow past a circular cylinder has been most widely studied ... -
On the Structure and Propagation of Premixed Flames in Turbulence
Turbulence interacts with flames over a multitude of lengthscales and timescales. These interactions are nonlinear and are ubiquitous, for example, in propulsion engines operating in space, air, land, and sea. ... -
On The Theory of burning of monopropellant droplets
