| Abstract: |
| The artificial bubble flow is triggered by the Pt micro-coheater guided by periodical pulse voltage in micro-channel,which is applied to restrain instability of flow boiling and strengthen heat transfer.Based on the hybrid multi-phase lattice Boltzmann model of larger density ratio,numerical investigation on fluid flow and heat transfer of artifical bubble flow in micro-channel is presented in this article.Through comparison of different frequency bubble flows,bubble motion and growth effect on fluid flow and heat transfer is quantitively analyzed.In addition,the micro-channel boundary effect on bubble dynamic behavior is also analyzed.The investigation results have presented a significant reference on study of flow boiling instability and heat transfer in micro-channel. |
