Summary0001957: Incorrect equation for Ks in long wave regime in LISA primary breakup model
in calculation of k in long wave regime (we<27/16) k = rhoAv*sqr(Urel)/2.0*sigma must change to k = rhoAv*sqr(Urel)/(2.0*sigma)

really, in k = rhoAv*sqr(Urel)/2.0*sigma ,first k1 = rhoAv*sqr(Urel)/2.0 and then k = k1*sigma ,but it is wrong and k= k1/sigma not k1*sigma.(refer to P.K. Senecal, D.P. Schmidt, I. Nouar, C.J. Rutland, R.D. Reitz, M. Corradini
    "Modeling high-speed viscous liquid sheet atomization"
    International Journal of Multiphase Flow 25 (1999) pags. 1073-1097)

 this mistake finally leads to wrong dD and SMD and should be correct.
