流道角度对PDC钻头热流耦合特性影响分析 : = Research on Influence of Angle of Flow Path on Heat-flow Coupling Characteristics of PDC Bit
利用计算流体动力学(CFD)对PDC钻头的不同流道角度下的温度场特性、对流换热特性及流道流场特性进行了热流耦合数值模拟分析,并试制样品及进行现场试验。结果表明,当PDC钻头每条流道中心线均经过内外切削齿与坯体形成的凹槽底面中点时,PDC钻头能获得更好的冷却及排屑效果,降低泥包现象,可进一步提高钻头的使用寿命。.
Computational fluid dynamics(CFD) was used to study the temperature field characteristics,convection and heat transfer characteristics and flow field characteristics of PDC bit under different flow path angle,and then the sample was trial-produced and the field test was carried out. The results show that when the center line of every flow path of PDC bit passes the midpoint of the groove bottom surface formed by the internal and external cutting teeth and the green body, the PDC bit can obtain better cooling and chip discharge effect, reduce the phenomenon of mud packing,and further improve the service life of the bit..
