【摘要】 塞形铜箔量热计在测量热流值高、冲刷大的场合应用十分广泛,但由于其偏离非理想条件和制作工艺造成的散差分布也比较大。从塞形铜箔量热计的测热原理出发,采用不同制作工艺制作了一批量热计,通过爆轰驱动激波管实验测量驻点热流值,根据实验结果分析不同的制作工艺对塞形铜箔量热计测量结果造成的误差,从而提高塞形铜箔量热计的散差分布。更多还原

【Abstract】 Plug-shaped copper foil calorimeter,which is widely used in harsh situations with high heat flux,has a poor consistency because of its deviation from the non-ideal conditions due to different fabrication processes.Base on the principle of the calorimeter, several calorimeters are manufactured by different fabrication processes,and are used to measure the heat-flux values at stagnation point of a serai-sphere model through detonation driven shock tube experiments.The experimental results are analyzed to find out feasible methods for improving the performance of the sensors.更多还原
