Abstract: In this paper, flow patterns, such as the velocity distribution along the radius of the nozzle block at section A-A and static pressure distributions along the nozzle block axis and its radius at section A-A, affected by the nozzle block’s structure parameters and the velocity at the jet orifice exit in Murata vortex spinning are investigated by the method of numerical computation. The results show that the tangential, axial and radial velocities inside the nozzle block are significantly affected by the jet orifice angle and velocity at the exit of the jet orifice as well as by the diameter at the inlet of the nozzle block. Static pressure distributions inside the nozzle block are significantly affected by the jet orifice angle, the velocity at the exit of the jet orifice, the outer diameter of the hollow spindle and the distance from the inlet of the nozzle block to the inlet of the hollow spindle.
