Nokia Uses Simulation to Analyze an Oscillating Piezoelectric Fan Blade
Akshat Agarwal, Nokia Bell Labs, Ireland
As electronics grow smaller and smaller and are used for extensive periods of time, their internal heat loads are greater and demand new compact cooling methods. Piezoelectric fans, a stepping stone between natural and forced convection, are one attractive option due to their low energy requirements. Engineers at Nokia Bell Labs are using multiphysics simulation to capture the interplay between an oscillating piezoelectric fan and the surrounding airflow in the pursuit of a quiet, reliable, and low-energy cooling solution.
