✦ Synopsis

The results of an experimental study of a temperature field and its statistical characteristics in turbulent water flow upon a sudden change of heat generation in the channel wall are reported. Measurements were performed in 5 mm x 40 mm, 10 mm x 40 mm, and 20 mmx 40 mm channels in the regions of thermal stabilization and stabilized heat transfer at Reynolds numbers of (0.8-6.8) x 104. The measurement results arc generalized using a dimensionless time scale. The results of the calculation of heat transfer coefficients at unsteady heat transfer are presented.
