Book excerpt: The major progress during the past year has been in these areas: (A) Calibration and modification of the heated test wall, (B) Development of data acquisition and reduction programs for fluid mechanics and heat transfer measurements, (C) Measurements of the baseline experiment on a flat surface, and (D) Literature search, design and fabrication of a three-wire probe for measuring Reynolds heat flux in a transitional boundary layer. The preliminary results of mean flow and temperature from the baseline experiment indicated that the test facility and apparatus are well controlled and adequate for conducting studies of natural transition boundary layers. The distribution of skin-friction coefficient and Stanton number has indicated a breakdown of Reynolds analogy in the transitional flow and was not recovered even in the fully turbulent flow regime in the present wind tunnel test section.
