Abstract:

THE DIFFUSION of temperature downstream of a step change in wall temperature or wall
heat flux in a turbulent shear flow is of interest from theoretical and practical points of view. It
is well known that. due to the quasi-linearity of the mean enthalpy equation, the solution to
the stepwise discontinuity in wall temperature can be used to calculate an arbitrary wall
temperature distribution [I]. Measurements. which have been made mainly in a turbulent
boundary layer [24]. have been useful for testing various calculation methods [5]. To provide
experimental data comparable to those previously obtained in a boundary layer. we
consider here a step change in wall heat flux introduced at one wall of a fully developed
channel flow (see Fig. I). The other (opposite) wall is maintained at approximately ambient
temperature. The results are compared with those for a thermally fully developed flow …
