REMARKS ON THE HEAT TRANSFER TO GASES IN TURBULENT FLOW BETWEEN PARALLEL PLATES
要約
Heat transfer to gases flowing with fully developed turbulent velocity profile between parallel plates has been investigated. The energy equation is written with the streamwise molecular and turbulent thermal diffusivities. The variation of density and viscosity with the temperature is taken into account by the introduction of a crosstream dimensionless coordinate
depending by the same variables. The energy
equation has been solved numerically with a
finite difference method. Heat transfer results,
for gases with Pr=0.7, are presented in the
ranges Re = 104−105 and TW/TB = 1.0−1.7, both
in the thermal entrance region and in the
following one. The predictions are compared to
the experiments performed in concentric annuli.
