Abstract:

Measurements in a fully developed turbulent channel flow with one wall heated at constant temperature and the opposite wall at approximately ambient temperature are compared with available direct numerical simulations. The consequences of the different thermal boundary conditions used in the experiment and the simulations are explored, especially with regard to distributions of the turbulent heat flux and the average production of temperature variance. In the near-wall region, the measured mean and r.m.s. temperature distributions are in good agreement with the simulations. Outside this region, differences exist mainly due to differences in the thermal boundary conditions at the opposite wall.

Heat transfer in fully developed turbulent channel flow: comparison between experiment and direct numerical simulations

Measurements in a fully developed turbulent channel flow with one wall heated at constant temperature and the opposite wall at approximately ambient temperature are compared with available direct numerical simulations. The consequences of the different thermal boundary conditions used in the experiment and the simulations are explored, especially with regard to distributions of the turbulent heat flux and the average production of temperature variance. In the near-wall region, the measured mean and r.m.s. temperature distributions are in good agreement with the simulations. Outside this region, differences exist mainly due to differences in the thermal boundary conditions at the opposite wall.
