4 main projects:1. Pressure and Velocity mapping of flow through a liquid acquisition channel (Dissertation)- Liquid acquisition device channels are used for delivering single-phase liquid when transferring propellant from a tank to another tank or an engine in zero gravity- Designed, built, and operated experiment for flow through a channel with one.

NASA Glenn Research Center, Cleveland, Ohio

The main focus of this internship was to develop, from the governing fluid dynamics equations, a solution to the 2-dimensional flow through a channel with one porous wall. Existing solutions in the literature were too simplified and either assumed a uniform velocity injection through the porous wall or applied incorrect boundary conditions on one or more.

This internship introduced me to screen channel Liquid Acquisition Devices (LADs), which are devices designed for transporting pure liquid inside of a space propellant tank to the outlet of the tank. In the reduced gravity conditions of space, buoyancy effects are negligible and the liquid and gas portions of the propellant can move very freely. The screen.

This internship consisted of both hands on and fluid system modeling work. I became familiar with fluid system components such as valves, pressure regulators, filters, relief valves. I had to order these components from vendors and also had to create an inventory of spares inside the warehouse. I learned how to size relief valves and how to model the flow.
