Shedding of Multiple Sessile Droplets
… vary. In this thesis, an experimental study on shedding of the multiple sessile droplets was performed on both hydrophilic and hydrophobic surfaces. The effects of the droplets arrangement type, and the spacing on Ucr were elucidate. For a pair of sessile droplets, a model was proposed to …

Computational modelling of vortex shedding flows
… of a two--<:limensional CFD method for vortex shedding flows past square and circular cylinders. The overall approach can be regarded as a compromise between the accuracy and computational costs, especially for high-Reynolds number flows. The latter are modelled by variants of the k - E …

Shedding light on E. coli phototaxis
My thesis work has been focused on phototaxis response in E. coli. I will review the current state of knowledge on chemotaxis and phototaxis and discuss the motivation behind this project in Chapter 1. In Chapters 2 and 3, I will describe a high-throughput framework for studying phototaxis in …

Vorticity shedding over two-dimensional bodies
The vorticity shedding characteristics in attached and separated regions were investigated over three configurations, namely a backward facing circular arc, an ellipse at an angle of attack and a pitching airfoil. A fully automated data acquisition system was developed, including a two-component …

Shedding Light on Biological and Ecological Function
Electronic spectroscopy is a technique which can be used to understand inter- and intra- molecular interaction, structure, coloration and function within biological and ecological systems. Herein, electronic spectroscopy will be utilized to evaluate novel fluorescence probes for studies of …

Global vorticity shedding for a vanishing foil
… of the phenomenon we call global vorticity shedding. Global vorticity shedding occurs when an object in viscous fluid suddenly vanishes, shedding the entire boundary layer vorticity into the wake at once. In our experiments we approximate the disappearance of a towed foil by rapidly …

Stability and Vortex Shedding of Bluff Body Arrays
… Particular attention was focused on the vortex shedding which was visualized and quantified through computation of the flow swirl, a quantity which identifies regions of rotary motion. The conditions required for the generation of leading edge vortex shedding were identified and discussed. …

A load shedding scheme for inverter based microgrids
… IEEE-13 distribution system was created. A load shedding scheme was developed in order to improve microgrid stability during fault provoked islanding conditions.

Analysis of vortex shedding in a various body shapes
… out to understand the phenomenon of vortex shedding. The simulation applied

Adaptive underfrequency load shedding based on real time simulation
Conventional Underfrequency Load Shedding (UFLS) is used to balance generation and load when underfrequency conditions occur. It sheds a fixed, predetermined amount of load irrespective of disturbance location. Several adaptive UFLS schemes are proposed in the literature. Recent research discussed …

Observational study of the monsoonal dynamics and eddy shedding phenomena
… vortices that then propagate away. Eddy shedding occurs in all four summers that we examined. We use the potential vorticity and Montgomery stream-function fields to document the characteristics of eddy shedding events. In most cases, the daughter cell propagates westward. In the …

Serviceability-based design of tall buildings subjected to vortex shedding
… across wind response caused mainly due to vortex shedding becomes a very important phenomenon that needs to be dealt with, and which also contributes a significant amount of acceleration on the building. Acceleration due to vortex shedding is the focus of this thesis. To determine a solution, …

WAMS-based Intelligent Load Shedding Scheme for Preventing Cascading Blackouts
… blackout. While traditional Under Frequency Load Shedding Schemes (UFLS) perform quick control actions to arrest frequency decline in an islanded network, they are not designed to prevent unplanned islanding. The proposed Intelligent Load Shedding algorithm combines the effectiveness of AGC Scheme …
