During the fall semester of my senior year, I took a thermal design course where we build upon our knowledge from previous courses, including fluid dynamics, thermodynamics, and heat transfer, in an application-focused setting (heat sinks, heat exchangers, etc.) along with learning several engineering design themes (optimization, economic analysis, etc.). Following the course material, we completed several projects, such as a custom heat sink and a pumping system. For our final project, we were given the freedom to create our own design problem. Seeing an interesting looking metal pipe in our professor’s office, me and my friend inquired and ended up centering our project around this device, a small scale pulsejet engine. Specifically, we were to design a static testing rig to cool the pulsejet during operation as well as measure thrust, which would be useful for future potential lab exercises for MECH classes. Cooling the pulsejet was critical because during static testing, there is no airflow to aid in convective cooling of the engine that it typically makes use of in operation. To make sure enough convection was provided, we conducted thermal analysis of the pulsejet alongside proper fan sizing. Ultimately, we found that our cooling system was not enough to allow safe steady-state operation, but we were happy with our robust thermal analysis and the design of our testing stand. Attached on this page are the report and slideshow presentation from our work.
