An Experimental Study of Surface Roughness Effects on Turbulent Boundary Layer Flow and Heat Transfer

Abstract

The uncertainty analysis, design, and qualification of a Turbulent Heat Transfer Test Facility (THTTF) with a smooth wall test surface are presented, and initial results for a test surface roughened with hemispherical elements spaced four base diameters apart are discussed and compared with calculations from a previously developed discrete element prediction method. A description of the facility and discussions of details of the instrumentation systems, calibration procedures and uncertainties associated with the measurements are documented. Keywords: Turbulence, Turbulent heat transfer.
