Matinpour Lab

Environmental Fluid Mechanics and Transport Phenomenon

The Matinpour Lab studies fluid mechanics and transport phenomena in environmental and engineered systems. We combine laboratory experiments with theoretical and computational modeling to examine mixing, constituent transport, particle segregation, and deposition across diverse flow environments. Our research aims to develop fundamental insights into complex flow systems with applications in environmental and geophysical processes.

Environmental Hydrodynamics and Water Quality

Study of flow, mixing, and constituent transport in rivers, reservoirs, and related aquatic systems through hydrodynamic and water quality modeling.

Multiphase and Particle Laden Flows

Study of suspension, segregation, and transport processes in viscous and turbulent multiphase flows involving particles, sediments, and mud-like materials.

Interfacial Transport in Engineered Systems

Study of deposition mechanisms and mineral scaling processes occurring near fluid-solid interfaces in engineered flow systems. This research examines how particles, minerals, and solutes interact with boundaries under varying flow conditions

Environmental Turbulence and Flow Dynamics

Study of turbulence-driven mixing and chemical transformation in environmental systems, including aerosol–turbulence interactions.
