Analysis of heat transfer and flow characteristics of a microcantilever beam for piezoelectric energy harvesting

摘要: Abstract This investigation is focused on studying the response and potential applications of a flexible piezoelectric microcantilever to harvest energy identifies pertinent parameters that govern its fluttering in flow. Piezoelectric materials have capability absorb mechanical which can be transformed into an electrical power low volt electric devices. The transport governing equations used this study were solved using finite element method. For microcantilever, fully coupled fluid-structure interaction (FSI) approach was solve for fluid structure interaction. Results obtained compared other analytical results from literature shown excellent agreement. illustrated significant effect inlet velocity magnitude deflection beam, output electric, heat transfer characteristics. Moreover, indicated as thickness material decreases, field increases. Further, average flux found increase significantly with velocity.
