When the inclination angle of a side nozzle is 0, 30,45 and 60 degrees, the eddying flow of the bottom hole vortex device will cause rotation at the bottom hole, affecting on the jet from bit nozzles.
侧喷嘴倾斜角度在0度、30度、45度和60度情况下，由于井底涡旋器的旋流作用，导致井底产生旋转，对钻头喷嘴射流产生了影响，以致在45度时出现压力损失最小的情况；
Based on this image, I am going to estimate each nozzle to have a radius of about 0.6 meters (although I think that estimate is a bit large).
根据这张图，我估计每个喷嘴的半径约0.6公尺(虽然我认为估计值稍微大了点)。
The influence of bit cutting teeth and its jet nozzle on the flow field is taken into account in the simulation.
模拟中考虑了钻头的切削齿和射流喷嘴对流场的影响。
