  title={High Frequency Surface Heat Flux Imaging of Bypass Transition},
  author={Richard J. Anthony and Terry V. Jones and John E. Lagraff},
A high-frequency surface heat flux imaging technique was used to investigate bypass transition induced by freestream turbulence. Fundamental experiments were carried out at the University of Oxford using high-density thin film arrays on a flat plate wind tunnel model. Bypass transition was induced by grid-generated turbulence with varying intensities of 2.3%, 4.2%, and 17% with a fixed integral length scale of approximately 12mm. Unique high resolution temporal heat flux images are shown which… CONTINUE READING
