Abstract
Newcastle University [UNEW] has enhanced the test section of their existing water channel facility. The new measurement section is utilized to measure pressure drop (and hence frictional drag) across a standard flat test panel (length=0.6 m; width=0.22 m). The panel can be tested as cleanly coated as well as exposed to light biofilm growth. Based on measured pressure gradients, the skin friction coefficients of these surfaces are calculated and compared with other well-established methods (i.e., measuring the boundary layer of similar surfaces using a [LDV] system in UNEW’s Emerson Cavitation Tunnel [ECT], to evaluate the pressure drop methodology. This paper presents a design and calibration of a flow cell to investigate skin-friction of three different surfaces in a fully developed turbulent flow.
