NUMERICS FOR LIQUID-GAS INTERFACES
Our group develops novel interface transport schemes with provable conservation, consistency, and accuracy. Beyond their natural application to liquid-gas flows modeling, these methods enable the numerical solution of discontinuous partial differential equations in general.
TURBULENT ATOMIZATION MODELING
Our computational schemes enable the investigation and modeling of complex turbulent liquid-gas flows with topology changes. Applications in energy sciences include fuel injection in gas turbines and scramjets, among others.
ADJOINT-BASED SPRAY CONTROL
We are developing a multiphase adjoint framework capable of producing reliable sensitivity information for realistic atomizing liquid-gas flows. This research will enable spray control and optimization with potential impact in broad areas of energy sciences and engineering.
NUMERICS FOR MESOSCALE SIMULATIONS OF PARTICLE-LADEN TURBULENCE
Our Euler-Euler and Euler-Lagrange computational methods enable the simulation of particle-laden flows at the mesoscale over a wide range of volume and mass fractions. These methods are designed to provide provable conservation, consistency, and accuracy.
STRONGLY-COUPLED PARTICLE-LADEN TURBULENCE
Particle-laden flows wherein both phases carry equivalent levels of momentum lead to strong interphase coupling that gives rise to poorly understood multiphase turbulence. Cluster-induced turbulence, relaminarization of the carrier phase, and new instability mechanisms have been found to occur.
