Flow modeling is an indispensable tool in reducing risk for industrial problems involving fluid flow.
Physical flow modeling entails the construction of a model, typically scaled so that the relevant geometry is smaller than the real-world prototype. Scaling laws are employed to make sure that the physical flow model behaves similarly to the full size prototype.
Gas flow modeling efforts (also referred to cold flow modeling or air flow modeling) are often deployed to industrial gas flow systems (such as air pollution control equipment), while hydraulic physical flow modeling efforts address liquid flow systems, particularly when a free surface is involved in the problem, such as a dam spillway or a wastewater pump station.
Flow modeling often involves the simulation of multiphase flow.
