TransAT Multiphase Flow Analysis Professional Software
TransAT Multiphase Flow Analysis Professional Software
Mainly used for numerical simulation of complex multiphase flow problems in the industrial field.
ABOUT software
Multiphase flow simulation analysis software TransAT was developed by the Swiss company ASCOMP, which is mainly used for numerical simulation of complex multiphase flow problems in the industrial field. TransAT software is based on the finite volume method, starting from the NS equation, and provides a complex multi-phase flow simulation program, which can be widely used to simulate single-phase and multi-phase compressible/incompressible flows, as well as evaporation and condensation, wetting processes, and phase separation , Capillary, Marangoni effect and other complex flow processes. So far, TransAT software has become a high-end analysis tool for multiphase flow and heat transfer.

The main function
TransAT is a multiphase flow numerical simulation (CMFD) software based on the finite volume method to solve the single-phase flow/multiphase flow NS equation. The software uses unique block structured grid technology (IST/BMR),
Can reduce the difficulty of meshing operations. The main functional modules are as follows:
