| Abstract: | Down-hole flow field study on air hammer drill bit helped to solve the cutting recycling and re-breakage problems. The methods, chief contents, primary results provided by the institutes as well as the major influential factors were introduced. Few studies were carried out on this iSsue nowadays, Computational Fluid Dynamics was recommended here, and in addition, experimental studies which offered the most reliable foundation should be involved if available. |
| Keywords: | air drilling air hammer bit down-hole flow field numerical simulation |
