Jessica Jourden presented, "Finite Element Model Characterization of a Regeneratively Cooled Nozzle"
Regeneratively cooled nozzles often circulate cryogenic compressed fuel through a nozzle composed of hundreds of tubes. This process cools and helps maintain the strength of the metal components during rocket engine operation. Engine designers use a simplified engine system finite element model to determine loads for component design. A two-dimensional shell mesh can be used for the nozzle in this load analysis model. Beam theory can be leveraged to compute approximate orthotropic material properties such that the shell elements will exhibit the same behavior as the nozzle tubes. A “truth model” can be made using cyclic symmetry. The mode shapes and frequencies of the shell model can be tuned to this truth model using Attune by adjusting the shell orthotropic material properties.

About the Series:
The Brown Bag Lecture Series is a tradition that gives select AE undergrads and grad students a unique opportunity to share their research before an audience that includes both their peers and their academic mentors and advisors.
