Determination of local fluid drag by a laser heating/thermographic phosphor technique: Applicability of the H. Ludwieg model
Technical Report
·
OSTI ID:6520674
A new application of laser thermography, that utilizes local heat- transfer measurements to deduce local fluid-induced drag is proposed and analyzed. The analytical model originally developed by H. Ludwieg is extended to account for heat conduction in the wall, and the limitations in Reynolds number that correspond to the Ludwieg assumption of a thin thermal boundary layer for air and water are discussed. 2 figs., 3 tabs.
