Interest for Simulation-Based Engineering Science (SBES) has grown exponentially from a curiosity to become one of the most promising areas of future research. With the rapidly increasing speed and performance of computers, SBES is becoming a key and central topic in both academic and industrial research. SBES offers excellent perspectives to propel Canadian university research to the forefront of international science while improving the profitability and competitiveness of Canadian manufacturing companies. In many instances, the complexity of natural and engineered systems arises from their multiscale and multiphase nature (e.g., mixing processes, microfluidic systems, emulsions, blood flows, oil and gas extraction, contaminants transport, to name a few). Our poor understanding of these complex flows hampers our ability to achieve the breakthrough to revolutionary design needed to improve the welfare of the Canadian populations. GOAL The long-term goal of this proposal is to encapsulate advanced knowledge and know-how in order to simplify access to and use of the Lattice Boltzmann Method (LBM) to improve the performance of multiphase flow systems relevant to industry. A FIRST axis of research on high-performance computing will develop a novel open-source framework for the simulation of multiphase flows. A unified programming approach and productivity tools will be leveraged to drive productivity and the adoption of our scientific research. This will provide a strong foundation on which to build SBES tools needed to tackle future industrial needs. A SECOND axis of research on numerical methods for multiphase flows will provide open-access information resources to make it easier for industry to consider and include multiphase flow simulations in their analysis and design practices. The development of new improved and efficient multiphase flow models will also place us in a favorable position to deal with new challenges. A THIRD axis on applications applies our research on two classes of multiphase flows problems that are of industrial relevance. The analysis and design of complex multiphase flow systems in porous media and static mixers will be explored to demonstrate the scope and breadth of our approach. The third axis addressing problems of industrial complexity will also significantly increase the impact of our research as these tools and approaches will be made publicly available. Together, this three-axis open-source open-access strategy aims to achieve a broad visibility and to develop a strong SBES scientific community around the proposed research program.
