Topology Optimization of Complex Thermofluid Flows and Systems: MultiPhysics Multiscale Modeling and Design

Abstract : Complex thermofluid flows like concentrated non-colloidal suspensions and fluid flows in porous media are present in many mechanical, chemical, geological, civil, biological, industrial and process engineering applications (e.g. blood, concrete, oil and fuels, cosmetics, detergents, drilling muds, rivers, food processing, cpu coolers, heat exchangers, etc). Developing advanced numerical methods and robust, reliable and sustainable Computational Fluid Dynamics (CFD) tools is very important. These numerical tools, thanks to the High Performance Computing (HPC) resources today (I.e. affordable clusters, cloud and parallel computing) permit scientists to deeply analyze different complex multiscale multiphysics phenomena. They allow deep analysis, understanding and knowledge of the different phenomena (multiphase fluid flow dynamics, heat and mass transfer) while reducing both time and money costs compared to mounting of expensive experimental setups. Topology Optimization of complex thermofluid flows and systems allow designing unpredictable artificially intelligent optimal components at different scales such as optimal heat exchangers, static and dynamic mixers, coolers, separators, heaters, air pollution filters, biogaz separators, etc. Topology optimization is known to produce optimal designs of complex geometries where the fabrication is not a big issue today ! This is thanks to the technology of additive manufacturing or 3D printing. The optimal component design produced by topology optimization can ensure different important features based on the user’s desired options such as: a maximum energy efficiency, a minimum weight, a maximum rigidity and a minimum pressure drop, all for predefined objective functions and at different industrial constraints. My research, development and innovation activities and scientific contributions during the last decade have been developing in this context. They are grouped into three major research axes or themes: Axis no.1 - Complex-fluid flows of non-colloidal suspensions, Axis no.2 - Topology optimization and design of complex thermofluid flow systems, and Axis no.3 - Multi-component fluid flows in adsorbent porous media. These three research axes have been contributing importantly to the scientific reputation of all my host research units during the last decade. They constitute a solid academic database and a huge potential for future scientific reputation. This is due to multiple undergoing scientific collaborations with different national and international universities, institutions and industrial partners. My research activities have been always developed trying to propose future solutions strategies in attempts to overcome some of the coming socioeconomic and industrial challenges (i.e. optimization and design of innovative components and materials, pollution reduction, energy savings and energy efficient new technologies).
