Purdue is known worldwide for its engineering department, offering one of the best programs in aerodynamics. Recent research topics from Purdue include computational fluid mechanics, separated flow around wings and bodies at high angles of attack, numerical methods in aerodynamics, aerodynamics of rotors and propellers, wakes and jets in V/STOL applications and aerodynamic noise, experimental measurements using laser systems, laminar-turbulent transition in high speed boundary layers and boundary layers. Purdue even has the Boeing Wind Tunnel -- a massive subsonic wind tunnel with two test sections equipped for high-lift research. It is also home to a number of Boeing laboratories that make this university a top choice for aerodynamics students.
If you want the international experience, Imperial College London has a fantastic aerodynamics department and the college falls under foreign schools covered by federal student loans. Students can enroll in postgraduate research programs for aerodynamics and fluid dynamics or structures and materials that can lead to a Ph.D. Areas of studies are taught by internationally recognized faculty members, and include the following areas: full speed range of low speed, transonic, supersonic and hypersonic flows. Turbulence and flow control are also included. Non-aerospace fields include biomedical fluid dynamics, marine technology, road vehicle aerodynamics, wave loading on offshore structures and wind energy.
If you are interested in pursuing a master's of science in the field, then you should consider California State University Long Beach and its Aerodynamics & Computational Fluid Dynamics (CFD) program that will lead to an M.S. in Aerospace Engineering. The program focuses on applied aerodynamics and aerodynamic design in various speed regimes. It also trains students in computational methods and tools for fluid dynamics. The program also includes advanced fields of study such as computational fluid dynamics I & II, advanced fluid dynamics I & II, aeroelasticity, and hypersonic flow.
The College of Engineering and Applied Sciences at University of Colorado Boulder offers courses that introduce the core principles and concepts of thermodynamics and fluid dynamic systems. Courses also stress the synthesis of physics, mathematics and experimental procedures that construct the foundation for quantitative and qualitative analyses of basic aerospace technology systems. One popular course offered is ASEN-3111 (4) Aerodynamics in which students learn the general concepts of aerodynamics and acquire a working knowledge of aircraft and design. They also become fluent with the designs and functions of launch vehicles operating at various speeds and altitudes and learn how atmospheric forces affect satellites.
