Our research centers around studying multiphase turbulence in the environment, with aims towards better understanding the fundamental physics of these flows, as well as better predicting and modeling their effects at scales where humans live. Research tools include Direct Numerical Simulation (DNS) and Large Eddy Simulation (LES) for simulating turbulence, and we partner with scientists making laboratory and field measurements. Our overall strategy is to build understanding from the small scales upwards: identifying fundamental interactions between individual grains of sand or spray droplets and the surrounding fluid flow, then building upon these processes to the macro scale.
One of our primary research tools is a simulation code built upon the National Center for Atmospheric Large Eddy Simulation Model. It is aptly named the NCAR Turbulence with Lagrangian Particles (NTLP; pronounced "enthalpy") code, and can be found here.
