Dr. Subramaniam’s areas of expertise are in theory, modeling and simulation of multiphase flows (including gas-solid flows, particle-laden flows, sprays, colloids and granular mixtures), turbulence, mixing, and reacting flows. His current research concerns direct numerical simulation of gas-solid flows, hierarchical coarse-graining approaches, and mesoscale models of colloidal aggregation. Application areas include riverbank water filtration, fluidized bed processes including chemical looping combustion and CO2 capture using dry sorbents.

Current Research Interests

1. Development of a two-fluid drag law for clustered particles using particle-resolved direct numerical simulation for CO2 capture in fluidized beds
2. Heat and mass transfer in gas-solid flows and circulating fluidized beds with application to CO2 capture
3. Stability of particle-laden suspensions
4. Modeling of cementitious pastes as a suspension using particle-resolved DNS and Discrete Element Method simulation of adhesive particles
5. Simulation of rapid and quasi-static granular flows using Discrete Element Method, and modeling using advanced continuum theories
6. Particle filtration in moving bed granular filters for biomass energy conversion
