Title: CFD Analysis of a 2D Rotating Detonation Engine Model
Detonation processes are combustion reactions in which the flame front moves supersonically. Such processes can have much higher thermodynamic efficiency than the more familiar deflagration (subsonic combustion) process used in nearly all of today’s engines. As such, engines are being developed that utilize detonation as their reaction mechanism, such as Rotating Detonation Engines (RDEs) in which a detonation travels continuously and indefinitely inside of a circular annulus. Unfortunately, many of these engines suffer from combustion instabilities and other phenomena that are not well understood and are influenced by a wide variety of factors, including everything from the RDE’s injection pressure to its circumference. As such, the goal of the research discussed during this presentation is to develop in ANSYS Fluent a functioning

Applications of SysML and other System Modeling Tools to Aerospace Systems
Organizing paperwork, data, and other relevant information for an engineering project can be messy and challenging, especially in the aerospace industry, as projects can often take years to complete. Currently, projects are often organized in a slew of spreadsheets and papers; SysML consolidates the clutter and creates one file for all the information to be stored and worked on collaboratively. SysML is a graphical systems modeling language that can be used in any engineering field, and this presentation will focus on its effectiveness to various aerospace systems. Specifically, its collaborative, data calculation, and requirement verification abilities will be highlighted.

Aircraft Braking Performance and Supersonic Aircraft
The first part of the seminar involves a quantitative analysis of aircraft braking performance. Aircraft landing safety is one of the most important concerns in the aviation industry due to the large number of accidents related to runway excursions. While many papers have explored the relationship between adverse weather conditions and braking performance, this research looks at things from a quantitative perspective by analyzing empirical data. The second part involves research around a supersonic aircraft's theoretical design, the automation of 2d supersonic inlets and CFD analysis, and component mass modeling.
