The retransition mechanism of a turbulent combined-convection boundary layer in air, which is generated by imposing an aiding uniform freestream on pure natural convection along a vertical isothermal heated plate, has been investigated experimentally and theoretically. It is confirmed that a linear stability analysis in a wide range of freestream velocities can well express the stabilizing behavior of the boundary layer, i.e., the calculated critical Grashof number increases exponentially with freestream velocity. In addition, the turbulence measurement with hot wires indicates that, as freestream velocity increases, the maximum intensity of temperature fluctuation decays exponentially, and a harmonic waveform with a specific frequency appears, which implies the presence of linear fluid motions. Then, a peculiar profile of the cross-correlation coefficient between velocity and temperature fluctuations appears independently of Grx, indicating that velocity and temperature disturbances have the same frequency with different phases.
