Jet-wake thermal characteristics of heated turbulent jets in crossflow

This paper is one in a series reporting on jets discharging to crossflowing water streams. The experiments were carried out in the 0.61-m x 1.067-m semiclosed circuit water channel at Iowa State University. Hot water was injected vertically upward from a circular pipe located near the channel bottom to simulate the turbulent heated jet. Contours of mean and root-mean-square temperatures both across and along the jet are reported up to lateral and downstream distances of 1.15 and 37 jet diam, respectively, and for velocity ratios of 1, 2, 4, and 7. The contours were used to explain the complex interaction mechanism between the freestream and the jet in both the jet and wake regions.
