    与其他类型压敏器件相比,接触式电容压力传感器(TMCPS)有着明显的优点,例如较好的线性,高灵敏度和大过载保护能力等。为了达到更好的性能,设计了一种新型的接触式电容压力传感器(DTMCPS),这种新型的结构是在传统的TMCPS的底部电极上刻蚀了一个浅槽。与现有的接触式电容压力传感器相比,这种结构可以实现更好的线性和更大的线性范围。使用有限元分析软件对膜片的变形进行了分析并阐述了传感器的结构和工艺过程。分析结果表明这种新型结构的传感器可以在保持传统结构优点的同时实现更高的灵敏度,更好的线性和更大的线性范围。Touch mode capacitive pressure sensor(TMCPS) has distinct advantages over other pressure sensors.To achieve better characteristics,a new type of touch mode capacitive pressure sensor named DTMCPS was devised,which had an additional thin notch on the bottom electrode of traditional TMCPS.Compared to present touch mode capacitive pressure sensors,the new sensor is characterized by better linearity and large linear operation range.Finite element analysis(FEA) was employed to model the structural deformation of this device.After that,the structure and fabrication process of the sensor were given

    Migration of carbon nanotubes from liquid phase to vapor phase in the refrigerant-based nanofluid pool boiling

    The migration characteristics of carbon nanotubes from liquid phase to vapor phase in the refrigerant-based nanofluid pool boiling were investigated experimentally. Four types of carbon nanotubes with the outside diameters from 15 to 80 nm and the lengths from 1.5 to 10 μm were used in the experiments. The refrigerants include R113, R141b and n-pentane. The oil concentration is from 0 to 10 wt.%, the heat flux is from 10 to 100 kW·m-2, and the initial liquid-level height is from 1.3 to 3.4 cm. The experimental results indicate that the migration ratio of carbon nanotube increases with the increase of the outside diameter or the length of carbon nanotube. For the fixed type of carbon nanotube, the migration ratio decreases with the increase of the oil concentration or the heat flux, and increases with the increase of the initial liquid-level height. The migration ratio of carbon nanotube increases with the decrease of dynamic viscosity of refrigerant or the increase of liquid phase density of refrigerant. A model for predicting the migration ratio of carbon nanotubes in the refrigerant-based nanofluid pool boiling is proposed, and the predictions agree with 92% of the experimental data within a deviation of ±20%
