Welcome

Welcome to the MIT Device Research Laboratory (DRL) under the direction of Dr. Evelyn Wang in the Mechanical Engineering Department at MIT.

The DRL combines fundamental studies of micro and nanoscale heat and mass transport processes with the development of novel nanostructured materials to create innovative solutions in thermal management, thermal energy storage, solar thermal energy conversion, and water desalination. We leverage state-of-the-art micro/nanofabrication, unique measurement, and model prediction capabilities to enable mechanistic insights into complex fluid, interfacial, and thermal transport processes. This approach has led to new and important functionalities to enhance heat and mass transfer for various applications.

Congratulations to the AeroShield Materials team (left) led by DRL alumni Elise Strobach and Kyle Wilke and others for winning the American-Made Solar Prize!

AeroShield Materials developed a flat-plate solar-thermal energy collector system that operates at more than 120 degrees Celsius with efficiencies greater than 45%. Transparent aerogel insulation enables this performance, minimizes heat loss, allows for simpler receiver design, and reduces cost. Aerogel lets light pass through but doesn’t let heat escape.

Congratulations to Youngsup Song for successfully defending his PhD on Mechanistic understanding and enhancing pool boiling heat transfer via surface property and structure design.

During his PhD study, Youngsup investigated the boiling crisis mechanisms during pool boiling associated with surface properties and structures through theoretical and experimental analysis. Based upon the fundamental understanding, he designed boiling surfaces that significantly enhanced the critical heat flux and heat transfer coefficient simultaneously. His thesis has important implications for a variety of boiling applications, where the reliable and accurate estimation and enhancement of boiling heat transfer are critical.

Congratulations to Arny Leroy for successfully defending his PhD on Subambient Passive Cooling Enabled by Polyethylene Aerogels.

During his PhD, Arny worked on the development, characterization, and optimization of polyethylene aerogels to achieve a low thermal conductivity material with high solar reflectance and infrared transmittance. Theoretically and experimentally, he investigated the benefits of using polyethylene aerogel covers in outdoor devices exposed to direct sunlight and demonstrated significant passive cooling below the ambient temperature and high subambient cooling power. His contributions show potentials of applications to food produce storage, building cooling, and reduction of CO2 emissions.
