Forced convection and nucleate boiling on a small flat heater in a rectangular duct: Experiments with two working fluids,a 50–50 ethylene glycol—water mixture,and water
The heat transfer characteristics for two working fluids, a 50–50 ethylene glycol—water mixture and water, on a small flat heater in a rectangular flow channel were examined for operating conditions in typical internal combustion engines. A particular effort was made to present robust heat transfer data without the constraints of the cross-section of the channel in the regions of forced convection and nucleate boiling, including the onsets of nucleate boiling. The effects of velocity, pressure, and subcooling were discussed using both boiling curves and visual observations.
