Reverse Circulation Bit Fluid Field Calculation

摘要：

Air drive reverse circulation bit interior fluid field analysis has relied on experiments for a long time. With the development of the computer, numerical simulation and emulation software brought many advantages contrasting the experiment. However, due to the complexity of the interior fluid field, few people have done the resolution calculation for it. In this article, through simplifying the air reverse circulation bit interior fluid field character, using the air dynamics and fluid mechanics to calculate the air distribution in the bit and the mass distribution equations have been obtained. It can be shown that the simultaneous equations have a unique resolution. The article provides help for making certain the bit parameters of the bit structure effectively studies the air reverse circulation bit interior fluid field character deeply.
