采用湍流κ-ε二方程模型对风琴管式喷嘴内外流场进行数值模拟，弄清其流场的流动特性（轴向速度、径向速度的分布规律和衰减规律），为提高清除岩屑效率提供依据。

The computationresults show that for a organ-pipe nozzle with a given configuration size, the nondimensional axial velocity attenuates slower with the increase in stand-distance, and the nondimensional axial velocity attenuation pattern remains the same, and the nondimensional axial velocity along the jet centerline attenuates slower with the increase in distance between the nozzleexit and the impinging plate.

计算结果还表明：对给定结构尺寸的风琴管喷嘴，随着喷距的增加，沿径向的无因次轴向速度衰减变慢、沿径向无因次轴向速度衰减规律不随喷速的变化而变化；无因次轴心速度的衰减规律随着喷嘴出口到井底间距离的增大，射流轴心速度衰减变慢，但其变化幅度不大；在固定靶距情况下，无因次轴心速度衰减规律不随喷速的变化而变化。
