摘要

本文对一种新型集成流量传感器进行了设计和建模,并在CMOS兼容技术下实现。该传感器设计用于瞬态速度和温度剖面应用中的气体和流体流量传感。这也出现在微流体中,当用微泵驱动时,会产生脉动流。对传感器进行了流体流动和传热分析。传感器的建模和优化给出了传感器的必要几何参数和材料的结果,以便在已知流体和给定流体速度和温度域的应用中最大限度地提高灵敏度。

Design and modelling for a thermal flow sensor
Design and modelling have been made for a new type of integrated flow sensor for implementation in a CMOS compatible technology. The sensor is designed for both gas and fluid flow sensing in applications with transient velocity and temperature profiles. This appear also in microfluidics where there is a pulsating flow when drive is made with micropumps. The sensor is analysed for fluid flow and heat transfer. Modelling and optimisation of the sensor give results for the necessary geometrical parameters and materials of the sensor for maximising the sensibility in applications with a known fluid and in a given domain of fluid velocities and temperatures.
