My current research project is on modelling the formation and growth of microsilica particles inside silicon furnaces, in collaboration with Elkem.
Microsilica particles arise as a byproduct of silicon furnaces, created inside high temperature flames due to the combustion reaction of silicon monoxide with oxygen. These nanoparticles grow as high saturated silicon dioxide vapour condenses on the surface of existing particles, and can also form aggregates. These particles are used in a variety of composite materials, such as concrete, and hence being able to control the size and quality of the particles is vital since this affects the performance of the material used for numerous applications. Motivated by this, our aim is to develop a mathematical model that relates the local fluid flow, thermal and chemical conditions of the furnace to the formation and growth of the particles.
