摘要：
The finite difference scheme developed by Liu et al. for the Newtonian jet swell problem has been improved: an algebraic approach has been adopted for the numerical mapping; a new formulation for free surface iteration has been proposed; the discrete flow equations have been solved by a combination of the successive line underrelaxation method and the Picard method. With these modifications we are capable of achieving more accurate numerical solutions and a substantial saving in computing time.
