Congratulations to Dr. Alex Carr on Defending his Ph.D.

My graduate student, Alex Carr, defended his dissertation on sonic boom through the turbulent atmosphere. Title: SONIC BOOM PROPAGATION IN THE TURBULENT ATMOSPHERIC BOUNDARY LAYER Abstract: Sonic boom waveforms measured at ground level exhibit variability due to scattering and diffraction caused by the presence of turbulence in the atmospheric boundary layer (ABL). Sonic boom propagation …

Laws of Thermodynamics
