Analysis of longitudinal velocity in the focusing tube of the abrasive water jet cutting head
Original language description
The analysis of longitudinal velocity in the focusing tube of the abrasive water jet cutting head serves for determination of the negative pressure in the mixing chamber of the cutting head. The value of the negative pressure is one of the boundary conditions for mathematical modelling of water jet flow through the cutting head. Several ways for determination of the interval of water jet exit velocities from the focusing tube into the free space were tested to evaluate the longitudinal velocity in the focusing tube of the abrasive water jet cutting head. The calculation includes the evaluation of the longitudinal velocity in the axis of water jet at the exit from the focusing tube, the calculation of the expansion velocity of water jet at its divergence in the air and the calculation of the mean velocity of the water jet by the end of the focusing tube. Specification of the mean outlet velocity from the mixing conditions is also performed.
