Process-Based Understanding of Ecosystem Carbon and Water Fluxes Using High-Resolution Remote Sensing
Earth’s terrestrial ecosystems are central regulators of the global climate system, mediating essential exchanges of carbon, water, and energy between the land and atmosphere. At the core of these dynamics lie two ... -
Studies on flow past pipe disturbances with Hagen Poiseuille approach flow
The problem of flow past disturbances in circular pipes has wide engineering applications. Most available information pertains to turbulent approach flow. In this thesis, the effects of disturbances in circular pipes are ... -
Chracteristics of self-aerated flows
A characteristic of high-velocity open channel flows is the phenomenon of self-aeration, in which atmospheric air is entrained into and mixed with the flow, creating the appearance of white water. This phenomenon is ... -
Division of flow in open channels
This thesis deals with the problem of division of flow when a branch channel bifurcates from a main channel. The effects of both the angle of off-take and the relative widths of the main and branch channels are considered. In ... -
Inception of cavitation
Cavitation due to flow separation may occur at pressures higher than the vapor pressure (e.g., where PwP_wPw? is the measured pressure in the cavity and PvP_vPv? is the vapor pressure at the corresponding temperature). The ... -
Separation control in diverging channels
The work presented herein consists of the separation control methods to minimize losses and recover as much velocity head as possible after the divergence in a straight-walled diverging channel in the subcritical flow ... -

Energy dissipation and other studies on submerged circular twin jets
When a high velocity sutmerged water jet enters a quiescent amhient medium of the same fluid Its energy gets gradually dissipated along Its course In the surrounding medium and Its efflux velocity gets decelarated along ... -
Some aspects of cavitation phenomena in centrifugal pumps
The work reported in this thesis has a fourfold objective, namely, to study: The influence of Froude number on the inception of cavitation in radial flow pumps. The influence of prerotation on the cavitation performance ... -
Effect of pre-rotation on cavitation in centrifugal and mixed flow pumps.
It has been theoretically shown that introduction of prerotation at the impeller inlet at design point improves the cavitation performance. A qualitative assessment of this from existing data on centrifugal pump impellers ...
