Secondary Droplet Breakup In Periodic Aerodynamic Flows Using Computational Fluid Dynamics, Krystle Gallo Jun 2012

Secondary Droplet Breakup In Periodic Aerodynamic Flows Using Computational Fluid Dynamics, Krystle Gallo

Honors Theses

Combustion instability is characterized by periodic fluctuations during the combustion process. Such instabilities can cause a reduction in engine performance and damage to engine components. In liquid fueled combustion, some types of combustion instability may be driven by changes in fuel droplet size distribution. The fuel droplet size distribution can be changed if the original or “primary” fuel droplets are broken apart by the flow. This is called secondary droplet breakup. The smaller drops that are created during breakup are consumed more rapidly and increase the energy release rate, which may act as a sustaining force of the instability. Currently, …


Development Of Oxidizer Flow Control For Use In Hybrid Rocket Motors Of The Scientific Sounding Rocket Scale, Luke Saindon May 2012

Development Of Oxidizer Flow Control For Use In Hybrid Rocket Motors Of The Scientific Sounding Rocket Scale, Luke Saindon

Honors College

To successfully build a rocket engine with variable thrust you must devise a reliable and robust oxidizer flow control system. The goal of this thesis is to contribute to the goal of building a variable thrust (throttled) hybrid rocket engine, which could eventually be used to power scientific sounding rockets. A variable thrust hybrid engine would increase reusability, flexibility, and capability of almost any small rocket.

Specifically, this thesis work regards the development of the closed loop oxidizer flow control system. To do this, a small test rig was built in the lab that consists of all the components in …

Applied Energy Systems: Hydrostatic Fluid Power Transmission And Flow In Pipes, Jim Mcgovern Jan 2012

Applied Energy Systems: Hydrostatic Fluid Power Transmission And Flow In Pipes, Jim Mcgovern

Book/Book Chapters

This is an intentionally compact textbook or set of notes for a module addressing basic Fluid Mechanics for incompressible fluids within the context of Applied Energy Systems. Rather than attempting to cover Fluid Mechanics in a very broad and general way, two practical areas are selected in the use of fluids: hydrostatic power transmission systems and the flow of fluids through pipes and fittings. This allows the two areas to be presented in some detail, but also allows them to be sample application areas that would enable learners to put the principles of fluid mechanics into context, while developing their …
