Title (EN) DEVICE AND METHOD FOR DETERMINING THE CONVECTIVE HEAT TRANSFER COEFFICIENT
(FR) DISPOSITIF ET PROCÉDÉ POUR DETERMINER LE COEFFICIENT DE TRANSFERT THERMIQUE CONVECTIF
(DE) VORRICHTUNG UND VERFAHREN ZUR BESTIMMUNG DES KONVEKTIVEN WÄRMEÜBERGANGSKOEFFIZIENTEN
Abstract:
(EN) The invention relates to a device for determining the convective heat transfer coefficient at a convection surface (1), wherein a first temperature difference between the surface temperature of the convection surface (1) and the surrounding fluid temperature and a second temperature difference between a temperature in the vicinity region (4, 20) close to the convection surface (1) and the surrounding fluid temperature can be determined. The vicinity region (4) is spaced from the convection surface (1) in such a way that the temperature is noticeably influenced by the convection surface (1) by convection.
(FR) L’invention concerne un dispositif pour déterminer le coefficient de transfert thermique convectif sur une surface de convection (1), ledit dispositif permettant de déterminer une première différence de température entre la température superficielle de la surface de convection (1) et la température de fluide ambiante et une deuxième différence de température entre une température dans la zone proche (4, 20) de la surface de convection (1) et la température de fluide ambiante. La zone proche (4) est située à proximité de la surface de convection (1) de façon à influer de manière notable sur la température de cette dernière (1) par convection.
(DE) Vorgestellt wird eine Vorrichtung zur Bestimmung des konvektiven Wärmeübergangskoeffizienten an einer Konvektionsfläche (1), wobei eine erste Temperaturdifferenz zwischen der Oberflächentemperatur der Konvektionsfläche (1) und der Umgebungsfluidtemperatur und eine zweite Temperaturdifferenz zwischen einer Temperatur im Nahbereich (4, 20) der Konvektionsfläche (1) und der Umgebungsfluidtemperatur bestimmbar sind. Dabei liegt der Nahbereich (4) derart nahe der Konvektionsfläche (1), dass die Temperatur von der Konvektionsfläche (1) durch Konvektion merklich beeinflusst ist.
