title: Structure of vortices in a karman street behind a heated cylinder
abstract: The velocity and temperature fields in a wake behind a heated cylinder are investigated for Reynolds numbers in the interval 65<Re<110. Spatial distributions of the amplitudes and phases of the first harmonics of velocity and temperature fluctuations in the region of formation of a vortex street are determined. A simple kinematic model is constructed to explain the evolution of the phase difference of the first harmonics of velocity and temperature fluctuations with increasing distance from the cylinder.
