While the traditional processing industries developed in the early 1900 when our ability to solve such complex multiphase flow equations were limited, the next generation of processing industries that rely not on fossil fuel, but on renewable bio-feedstock, can be built using modular technologies with design tools built on strong foundational mathematical models for multiphase flows. The BIRS workshop will bring together mathematicians, scientists and engineers working on this field to learn from each other the current state of the science of multiphase flows to enable such innovations.
