Aero-propulsion research is at the forefront of advancing air-transport technology for civilian, military, and space applications. Two key components of this technology include aerodynamics and propulsion systems, which inherently operate on principles of fluid mechanics. In this talk, we will first discuss the crucial role of scientific computing in providing high-fidelity simulated data on fluid behavior in aero-propulsion systems. Focus will be on the nature of relevant governing equations, and the specific numerical and computational techniques tailored to solve these equations in the context of aviation systems. In the second part, we will summarize two ongoing research programs at our lab: computational aero-acoustics, and hypersonics. In aero- acoustics research, we utilize simulations of supersonic flows to identify sources of intense sound emitted by Naval aircrafts, which are detrimental to the environment. The goal is to curtail these sources to reduce impact of military aviation on our surroundings. In the hypersonics task, we identify mechanisms that induce fluid turbulence in highly-compressible flows, which is a major roadblock to increasing the speed of air travel. We will discuss the computational approaches to solve the linearized and non-linear governing equations, and their respective roles in identifying the causes and effects of turbulence in hypersonic flows.
