The capabilities of the Taylor analogy breakup (TAB) and wave breakup (WB) spray models, already existing in the literature, were evaluated in KIVA-II code. Also, a novel droplet deformation and breakup (DDB) model that takes into account the nonlinear effects which manifest at large deformation of the drops was incorporated and tested in KIVA-II. The assessment of the three models was performed by using experimental measurements of tip penetration, spray cone angle and Sauter mean radius (SMR) in a cylindrical optically accessible closed vessel at room temperature and high gas density. High speed photography and laser light extinction techniques were simultaneously used to detect data along a n-heptane jet coming out from a single hole nozzle of 0.20 mm diameter supplied by PE-Bosch injection pump operating in single shot by electro-hydraulical device. The KIVA calculations with TAB model in terms of penetration and SMR do not predict accurately the experiments.
