Mechanical and Thermal Engineering Sciences

The Mechanical and Thermal Engineering Sciences (MTES) directorate at NREL drives technological innovation in the areas of energy efficiency, sustainable transportation, and renewable power. We provide engineering and scientific expertise to a variety of federal agencies, including the DOE Office of Energy Efficiency and Renewable Energy, Office of Science, and ARPA-E, as well university and industry partners. The directorate is led by Associate Laboratory Director Dr. Johney Green Jr.

Featured Project

NREL Senior Scientist Kenny Gruchalla, examines the velocity field from from a wind turbine simulation using a 3D model at the Insight Collaboration Laboratory during a tour of the Energy Systems Integration Facility (ESIF) at the National Renewable Energy Laboratory (NREL) in Golden, Colorado.

To reduce the cost of wind energy, we must be able to predict the complex flow physics in wind farms. Through the ExaWind project, NREL is partnering with Sandia National Laboratories and scientists at Oak Ridge National Laboratory and the University of Texas at Austin to develop new simulation capabilities to improve our understanding of the performance of whole wind plants. ExaWind is part of the Exascale Computing Project, a joint effort between the DOE Office of Science and the National Nuclear Security Administration. Learn more about ExaWind.
