Dr. Kurt Aikens joined the faculty at Houghton College in 2014 after completing his Ph.D. at Purdue University. His research interests are in aerodynamics and include both experimental and computational approaches. More specifically, his research focuses on improving computational methods for accurately predicting – and ultimately reducing – jet engine noise. This is in the greater field of computational aeroacoustics and includes: large eddy simulation for predictions of turbulent flows, integral acoustics methods for propagating noise to the acoustic farfield, high-resolution shock-capturing methods, high-performance parallel computing, and wall modeling to reduce time-step restrictions for wall-bounded flows.

Purdue University, School of Aeronautics and Astronautics, West Lafayette, IN

Research Assistant, “Realistic Simulation of Jet Engine Noise Using Petaflop Computing”, 2012 – 2014

  • Oversaw the completion of an XSEDE proposal for computing resources on top supercomputers.
  • Added shock-capturing methodologies to a highly-parallelizable (tested on up to 90,000 cores) code for accurate resolution of nearly discontinuous solutions.
  • Extended code to include converging-diverging nozzle geometries to improve simulation fidelity.
  • Collaborated with computer scientists to improve code performance.
  • Implemented a wall model to reduce computational expense of including nozzles in simulations.
  • Performed in-depth flowfield and acoustic analysis of beveling the nozzle exit for reduction of jet noise.
