✦ Synopsis

Experiments were performed to determine convection heat transfer characteristics for the rounding of the protruding peaks of a corrugated channel. Results were carried out for a Prandtl number of 0.7 in the Reynolds number range from 2000 to 5000 for the corrugation angle of 30 o and channel height of 5 mm. In order to determine the channel having the best performance, the channels were also compared by considering the flow area goodness factor. The heat transfer performance for the channel with rounded corrugation peak is greater than that for the sharp peak about 100%.

An experimental study was conducted to investigate how the addition of small amounts of a surfactant influences the heat transfer characteristics in a thin boiling liquid film flowing in a diverging open channel. Heat transfer experiments were conducted with fluid inlet temperatures from 40 °C to 92
