Abstract:A conventional, cold-wire technique is used to provide a more detailed description of the time-resolved structure of a thermal boundary layer in the oscillating flow. The cold-wire technique provides for increased data acquisition rates relative to CARS, at the expense of an ambiguous, systematic error associated with the intrusive nature of the probe. The cold-wire technique is used to investigate oscillating boundary layer flows with differing degrees of periodic flow reversal. Local, time-averaged Nusselt number results for the oscillating flow are a factor of two higher than accepted values for a laminar, developing channel flow. Periodic flow reversal did not provide a heat transfer advantage relative to non-reversed oscillating flows.
