QuasiPAS Model Using The Fourth, Fifth and Sixth Positive Root of j2(x) and j3(x)

Abstract

QuasiPAS flow was invented by Bachtiar and James (BJ 2011). They modified Pekeris, Accad and Skholler PAS dynamo in order to get a new flow which can be fully planarized. BJ evaluated three types of quasiPAS flows: basic, partly-planarized and fully planarized. They used the first three positive roots of spherical Bessel function order two. They found nine new dynamos, unfortunately none of them is a planar velocity dynamos. In this paper, we revisited one of their flows, which is the unplanarized quasiPAS, using the fourth, fifth and sixth positive roots of spherical Bessel function order two. We found no new dynamo, but we predict that higher resolutions are needed in order to get more conclusive results.
