Abstract: Present study mainly focuses on the dispersion simulation of cooled water discharged by LNG terminal which is under construction in Manzanillo, Mexico. CORMIX and VISJET models are applied to simulate the behavior of negative buoyant jet. The results show that the degree of negative buoyancy does not show crucial influence on the dilution rate because initial momentum is dominant in the near-field region. In case of no ambient current, dilution results by empirical equation, CORMIX and VISJET appear to be in good agreement with others. However, as the ambient current speed increases to 1.0 m/s, VISJET gives higher dilution compared with the value of dilution equation or CORMIX. This result arises from the fact that assumption of merging between nearby jets is not adopted in VISJET model.
