Our Projects
Turbulence is the primary paradigm in natural systems, such as, Oceanic, Sea-Ice, and Atmospheric systems, and engineered systems. Our research includes both fundamental research to understand the nuances of turbulence, and also applying the concepts of turbulence to solve engineering and geoscientific problems. We use massively high-performance computing, field experiments, and sensors and intelligence systems to answer fundamental questions on turbulence.

Wall-bounded Turbulent Flow Over Roughness
Overview: DNS with immersed boundary method has been developed to simulate rough-walled channel flow.
Buoyancy-Driven Turbulent Flows
Overview: LES tool has been developed to simulate geophysical scale Buoyant plumes in a stratified environment to address fundamental questions on Buoyant Turbulent flows
Wake Effects of Wind Turbines
Open-foam SOWFA solver has been used to simulate full-scale wind turbines subject to Atmospheric Forcings.
Density Currents Over Rough-surfaces
Overview: DNS and LES solvers have been developed to simulate density currents over rough-surfaces. Lock-Exchange Density currents and Overflows have been studied to answer fundamental question on entrainment and mixing processes due to bottom roughness. The work has implications in oceanography and global circulation
Multi-Sensor Fusion for Drift Prediction in the ocean using a moving platform
Overview: An interdisciplinary approach using hardware integration (LiDar, Camera), machine leaning and fluid dynamics has been developed for drift and drag estimations of objects lost in the ocean due to atmospheric and oceanic forcings.

Turbulence in WildlandFires
Overview:WRF-LES-bplume model has been developed to simulate smoke and thermal plumes during wildland fire events. The effects of atmospheric stability, surface heat flux has been analyzed on entrainment and plume spread
Experimental and CFD analysis of UAV propeller turbulence
Overview: Tests are being conducted on DJI Matrice 600 and 100 systems to understand the interaction of propellor blade turbulence with ambient turbulence. Wind and environmental sensors are mounted on UAV/UGV platform
