Abstract
DILUTE polymer solutions which exhibit detectable elastic effects can produce large reductions of fractional drag over fully rough surfaces in the absence of any viscous sublayer1. We have carried out some heat transfer experiments with polyethylene oxide (Union Carbide Polyox WSR301) solution in a rough bore pipe and derived some interesting results.
