The budgets of turbulent energy, Reynolds shear stress, mean square scalar variance and turbulent heat fluxes have been evaluated in a thermally driven boundary layer in air along a vertical flat plate. In the near-wall region, the velocity-gradient correlation plays an important role in turbulent energy production, and thermal energy is directly converted into kinetic energy through this correlation. Consequently, Reynolds shear stress and streamwise turbulent heat flux near the wall, which are normally considered to be closely related to the energy production process, behave differently from those in the ordinary turbulent boundary layers. On the other hand, the energy transfer in the outer region of the boundary layer becomes a process similar to that observed in the usual boundary layer.
