Design and Simulation of Multi-Microchannel for Thermal Wind Sensor

Abstract:

This paper describes novel multi-microchannel, which is the major component of wind velocity and direction sensor based on MEMS technology. The multi-microchannel built in a cylinder, and the channels have been optimized to produce a flow rate that depends on the wind direction according to a cosine function. When two such cylinders placed orthogonally in wind condition, wind speed and direction can be inferred from flow rate data measured from the channels. With the help of Fluent simulation software, this paper not only provides the design ideas of multi-microchannel but also proposes one design approach which meets the practical needs.
