Multiphase Systems

Many flows in nature and industry involve multiphases. By making a sustained, substantial investment in advanced technology development — and focusing on reliable, fundamentally sound physical model development — ANSYS has  developed  an impressive range of multiphase flow modeling capabilities and the associated engineering experience to help researchers, process engineers and equipment designers to enhance the performance of complex multiphase systems. ANSYS provides an unparalleled depth of capabilities for modeling these systems, which include heat and mass transfer with or without reaction, including free surfaces, gas–liquid, gas–solid, boiling, cavitations, wet steams, flashing, slurries, and particulate systems.

Reflecting its commitment to this technology area, ANSYS offers a number of unique capabilities tailored to multiphase modeling requirements. For example, ANSYS simulation tools allow engineers to model particle size distribution through population balance, combining detailed fluid mechanics analysis with a better description of the size distribution of particles, bubbles or droplets in a multiphase mixture. This approach accounts for phenomena such as nucleation, growth, dispersion, dissolution, aggregation and breakage. By employing ANSYS tools, engineers can describe and track changes in the particle population.
