Five kinds of multi-head burners with different structures were discussed according to potential flow theory in this paper.Three cases were selected for further numerical simulation from the consideration of cross fire, wall temperature and flow field.The influence of the rotation direction of the main stage and central class burner on the combusti

Electromagnetic response of metamaterials is Bath not only determined by its component materials but also the microstructure and arrangements of its resonant elements.The perfect absorber prepared by metamaterial (PMA) can realize 100% absorption in specific frequency bands by designing reasonable structures of resonators.PMA can be applied in many
