Abstract:
Mean wind velocity and temperature profiles were measured in a wind-tunnel boundary layer (approximately 1m thick) made thermally stable or unstable by flow over a horizontal flat plate (29 m long, and 2 m wide) which was either cooled or heated along the downstream 13 m. Laboratory and field mean velocity profiles were found to be similar as were the mean temperature profiles when compared on the basis of a log-plus-linear relationship. For thermally unstable flows, the dimensionless wind shear is approximated by the form (1+z/L)n with n = 32. The transition from forced- to free-convection flow for unstable stratification was gradual and occurred in a Richardson number range predicted by Gurvich and Priestley. Both laboratory and field data for ζ & lt; 0 are best represented by a function of the form Ri = −(1−S2/3/αS).
