Abstract
The use of a modified Gardon-type heat flux meter [2] for measuring the local boiling heat flux density around a large diameter horizontal cylinder which is quenched from a high temperature in saturated or subcooled water is described. The fabrication and calibration procedures are provided along with a detailed conduction analysis of the temperature field in and around the meter. An approximate boiling heat flux density-vs-temperature curve is predicted from the measured cooling curve for a point on the cylinder. It is shown that this boiling curve agrees well with that recorded by a calibrated heat flux meter. It is concluded that heat flux meter can be used effectively to provide reproducible measurements of the entire boiling curve during quenching experiments.
