Location: RWTH-Aachen. The workshop should promote the exchange of new ideas and results related to modeling aspects and the development and application of efficient numerical methods for the simulation of two-phase incompressible flows. The topics include: surfactants and Marangoni effects, numerical treatment of surface tension, level set methods, adaptivite methods, mass conservation, parasitic currents, engineering applications.

The successful candidate will have expertise in large-scale computations, modeling and analysis of dynamical systems. Particularly sought are candidates with knowledge of dynamical systems theory and demonstrated skills in asynchronous computations for large dynamic networks, computations on graphs; and modeling and computations in a parallel environment (100+ nodes). Knowledge of one or more of the following disciplines is desired: control theory, optimization, model reduction techniques, numerical analysis, computation for systems with uncertain parameters (stochastic finite elements, polynomial chaos, stochastic response surface methods), and/or Markov Chain methods. Previous experience with applications of such methods for large, complex engineering systems and large dynamic networks is highly desirable. Besides technical excellence, very strong teaming and communications skills, together with an entrepreneurial attitude towards innovation, are essential. The minimal education requirements are a Ph.D. in mathematics, computer science, or engineering, or an M.S. in the same area supplemented by 5 years of industrial research post degree. The System Dynamics and Optimization Group at United Technologies Research Center works within integrated product development teams to design, analyze, and implement systems solutions and conduct model-based analyses for new products and processes. The traditional areas of strengths of the group are multi-scale and parametric analysis of nonlinear systems, modeling of thermo-fluids and reacting flows, computational complexity reduction, advanced signal processing, classification and decision support tools. Applications currently under study include building security systems; advanced modeling environments; uncertainty propagation through large, complex networks of systems; fuel cell power plants and advanced fuel processing systems; refrigeration systems; elevator positioning; decision support tools built upon statistical and physics-based models of wear; and strategic business decision support tools.
