The Multi-Scale Heat Transfer (MHT) Laboratory focuses on theoretical, numerical and experimental studies in Heat Transfer and Mass Transport Enhancement in Micro, Meso and Nano Scales, in Single-Phase and Two-Phase Flows, in the Presence and Absence of Gravity
The MHT Laboratory also focuses on Electrohydrodynamics (EHD) in multi-scale and multi-phase, on heat and mass transfer in porous media (Drying), on the enhancement of forced and free convection heat transfer using micro-encapsulated phase change materials (MEPCM) and on the augmentation of heat and mass transfer using innovative impinging jets. Research at the MHT Laboratory also includes the development of EHD actuators, two-phase heat transport systems for space/microgravity applications, and pumping of micro liquid films for flow management in phase change devices.
For example, the laboratory features custom-made single-phase and two-phase electrically driven heat transport devices and state of the art two-phase flow experimental apparatuses. A unique facility for measuring the electrical conductivity and permittivity of dielectric fluids within a wide range of temperature and pressure is availble in the laboratory as well as equipment for observation of phase change in condensation and evaporation.

$2.75 Million DOE Grant Awarded for Energy Research
MHT director, Jamal Yagoobi, is leading this exciting new research that will drastically cut emissions and energy use.
MHT director and founding CARD director, Jamal Yagoobi, along with his research team have been awarded a $2.75 million U.S. Department of Energy grant to drastically cut emissions and energy use in industrial drying.
His team has been working on ways to dry paper, pulp, and other materials using the concentrated energy found in lasers. The lasers Yagoobi’s team uses are not the lasers of the public imagination. Though the lasers are quite strong — they can melt metal — they are dispersed over a larger area, spreading out the energy to evenly and gently dry the target material. Read more.
Working with NASA on Cooling System that Facilitates Space Travel
An MHT research team led by principal investigator, Jamal Yagoobi, has developed a cooling system that will help keep astronauts and electronic equipment cool during space travel. The Teflon-like material prevents components like satellites and space stations, as well as space travelers, from overheating. The technology, which was developed in collaboration with colleagues from NASA, uses charged fluids to absorb and remove heat and has been tested in zero gravity.

Nathaniel O’Connor, along with Alexander Castaneda and collaborators from Goddard Space Flight Center, performed EHD experiments on several parabolic flights. These experiments provided valuable microgravity data to the team, paving the way for sending the Electrically-Driven Liquid Film Flow Boiling experiment to the International Space Station.
