Flow Simulation Technology

CFD (Computational Fluid Dynamics) is a powerful tool for analyzing the phenomena associated with the fluid flows in a variety of industrial fields. Thanks to the utilization of this powerful tool, JGC is able to carry out optimum designs, quick and rational scale-up of various types of industrial equipment and apparatus. At the same time, these CFD technologies are well integrated with the reliable technical know-how and expertise supported by the abundant experience of CFD application in the field of plant engineering.
