Numerical Simulation of the Flow Field Influenced by the Frequency of Piezoelectric Fan

Piezoelectric fan is a miniature cooling component, which with some advantages such as small, thin, low- volume, and low power consumption etc. Piezoelectric fan can be used in small electronic cooling products, but there is no research focusing on that the frequency of piezoelectric fan produces an effect on flow field behavior. And the study in this article is adopting commercial CFD software Fluent to investigate the behavior of flow field influenced by the frequency of piezoelectric fan in rectangular flow channel, the study uses numerical simulation methods to discuss 1. Mutual relationship between the frequency of Piezoelectric fan and the frequency of the generation of vortex and disappear; 2. Mutual relationship between the frequency of piezoelectric fan and the vibration frequency of flow field.
