  A Comparative study of the strengths and weakness of the models of fireball
formation namely the statistical model of Ramanathan et.al (Physical Review C
70, 027903, 2004) and the approximation schemes of Kapusta et. al (Physical
Review D 46, 1379, 1992) and its subsequent improved variants is made. The way
to complement the various approximation schemes, in order to enhance their
utility in the phenomenological analysis of QGP data that are expected from
ongoing URHIC experiments, is suggested. The calculations demonstrate a
striking QCD behaviour of the surface tension of the QGP droplet resulting in
its increase with temperature, which is due to the confining nature of QCD
forces at the surface and the interface surface tension varies as the cube of
the transition temperature which is in conformity with the results of Lattice
QCD simulations.
