713 Complex Fluid Flows in Engineering: Modeling, Simulation and Optimization

The design process in engineering applications is currently experiencing a change in paradigm away from experience-based design to numerical design. In many such engineering applications, flows of complex fluids are encountered; posing the challenge of understanding, describing, computing, and controlling these flows. In this spirit, this minisymposium aims at providing a forum for questions concerning both numerical and optimization methods specific to fluid flow. On the modelling-side it covers the issues related to complex, non-Newtonian flow phenomena, such as choice of model or appropriate stabilization. Furthermore, in the area of simulation, novel numerical methods, ranging from discretization methods to both free-boundary problems and deforming domain problems, are considered. In all cases, the flow solution may serve as the forward solution of a shape optimization problem, requiring a shape representation and a design objective along with problem-specific optimization schemes.
Topics of this minisymposium include, but are not limited to:
o Methods particular to specific applications such as primary manufacturing processes, dam breaks, industrial storage tanks, combustion engines, ship design, etc.
o Non-Newtonian fluid models describing shear-thinning or viscoelastic properties, e.g., Carreau-Yasuda, extended Pom-Pom, Phan-Thien-Tanner, Giesekus, etc.
o Simulation methods including stabilization schemes, interface capturing, and interface tracking.
o Methods and applications related to shape optimization in fluid flow, e.g., geometry representation, boundary conditions on the shape, or choice of objective function.
