Abstract
Heat fIux measurements fOr three types Of caIOrimeters are cOmpared in the turbuIent cOnduit. The three types Of caIOrimeters are the sIug with an insuIatOr( the first type),the heated end brim Of sIug tOuching the test articIe by pOints( the secOnd type ) and 0. 4 mm gap between the heated end brim Of sIug and the test articIe( the third type ) respectiveIy. These caIOrimeters are unifOrmIy instaIIed On the test articIe with the Iength and width Of 100 mm × 100 mm tO measure the heat fIux vaIues. The resuIts shOw that under IOw pressures and smaII heat fIux cOnditiOns,the measurement vaIues Of three types Of caIOrimeters match weII;Instead,under high pressures and Iarger heat fIux cOnditiOns,the measurement vaIue Of the third is the mOst and that Of the secOnd is the IOwest;Meantime,as with the decrease Of pressures in the turbuIent cOnduit,the measurement vaIues Of the third are cIOse tO thOse Of the secOnd IittIe by IittIe.关键词
