The 2PFG counts on the computational fluid mechanics laboratory which has 10 computers based on Intel and AMD single processors and one Dell Precision^TM based on Intel dual core processor, a scanner and two printers: a laser and an ink jet. Most of the analytical models are developed using high level programming languages such as Mathematica or MATLAB. The group also has a permanent site license of Phoenics, a commercial CFD code with three dimensional two-phase flow capabilities which allows the development of user-defined Fortran subroutines. In addition the group also develops its own softwares using the Compaq Visual Fortran. The typical works using Phoenics employ particle tracking algorithm, two-fluid model and the VOF method. The numerical techniques give us a valuable tool to develop physical models, enhance the physical insight and complement the experimental data.
