Particle-Laden Flows

Many industrial processes involve flows that contact a gas with a semi-dilute suspension of solid particles or drops to achieve heat and mass transfer, catalytic reaction, combustion and separation of the particle phase. Despite their practical relevance, particle-laden flows are not fully understood owing to the intricate coupling between the dispersed and continuum phases. To shed light on the dynamics of these flows, my work focuses on expanding two axes:

• Developing robust and efficient numerical tools in Euler-Euler and Euler-Lagrange formulations.
• Uncovering and analyzing fundamental instabilities in the presence of two-way coupling.
