1963 — A heat transfer probe for use in a high temperature gas.Résumé
This report deals with the analysis, design and construction of an instrument intended to measure gas temperature in excess of 2000°C. Preliminary experimental calibration of this instrument is compared with those two particular aspects of theoretical behaviour which have been dealt with. A platinum/platinum-rhodium thermocouple was used in calibration to a temperature of 1300°C. The instrument is a conductive-convective heat flux device. A fine stainless steel tube is heated by the hot gas and cooled internally by flowing water. The water is supplied by and returned respectively, through one of two copper tubes inside a water cooled stainless steel jacket. … Lire la suite
