Abstract

In this presentation, I will review how in the past 5 years significant progress has been made in the MPESG Group, based in Aeronautical/Mechanical Engineering at Salford University and Think Lab to develop new models for functional smart coating flows. ➢ Our focus has been computational multi-physical fluid mechanics and applications in 3 main areas - aerospace, energy and medical engineering. In this presentation we will cover: ➢ 1] A brief overview of our group and explain what engineering multi-physics is & how we do it (bearing in mind many of you are materials scientists and not fluid dynamics people!). ➢ 2] We will then describe types of advanced functional materials used in coatings and their stimuli e.g. functional metallic polymer materials (organo-metallic polymers, electro-responsive liquid metal-polymer hybrids, photo-rheological fluids etc). ➢ 3]Next we will briefly review advanced simulations of electro/chemo/magneto/nano functional material coating flows on a variety of different substrates (i.e. geometries being coated - we consider plane surfaces, circular disks and cylinders), different constitutive (rheological) models and numerical methods coded at Salford for solving the resulting “boundary value problems” . Visualization of flow, temperature, concentration (species) fields is emphasized. We employ a continuum “boundary layer” approach, not a molecular dynamics approach. Prandtl’s boundary layer theory is a robust fluid mechanics framework originating in aerodynamics and gives more insight into the near-wall phenomena. ➢ It is important to note that Computational Fluid Dynamics is much broader than commercial software alone e.g. ANSYS suite, STAR, PHOENICS, ADINA - it also has a very rich area of diverse numerical methods and material models which are NOT provided in these software. ➢ 4] Finally we will show the most recent MPESG research directions e.g. laser-assisted super-paramagnetic coatings, electromagnetic actuator modelling etc. ➢ The emphasis throughout is from a fluid dynamics perspective of materials ! Apologies for the mathematics to metallurgists- it is the nature of the beast! (to quote the great aerospace engineer, Dr. Theodore Von Karman, incidentally the best student of Prandtl.)
