The Small and Smart Thermal Systems Laboratory (S2TS) at the University of Maryland, College Park, is engaged in cutting edge research in the fields of advanced heat and mass and thermal management systems. The research at S2TS is of particular significance to applications in advanced energy conversion, advanced heat/mass exchangers, process intensification, electronics cooling, and innovative design and manufacturing of components for energy conversion systems. Through innovative research and technology development activities we strive to anticipate the needs of our sponsors and exceed their expectations. Our research projects also include innovative and advanced manufacturing techniques for energy conversion and thermal management applications. This includes emerging fields such as additive manufacturing and the use of micro and nano systems for process intensification and optimization.

Since its inception in 1993, the S2TS Laboratory has been involved in a number of basic and applied studies in the field of active and passive heat transfer augmentation techniques, mass transfer, and energy conversion. Over the years, the Laboratory has successfully developed the technical know-how and the knowledge base critical to the incorporation of emerging technologies into practical applications ready for commercial use.

Through its affiliation with the Computer Aided Life Cycle Engineering (CALCE) Center and the Center for Environmental Energy Engineering (CEEE), the laboratory is dedicated to developing advanced heat exchangers and smart thermal management techniques as solutions to future thermal systems.

Our Laboratory may be best known for its contributions to development of small and smart thermo fluidic systems through the Electro Hydrodynamics Technique (EHD). The EHD technique utilizes an inducted electric field to promote and manipulate fluid flow and thermal fields in a given application. Among other advantages, EHD may be particularly suitable for applications in which active (online/on demand) control of a process is necessary.

With the aim of creating more sustainable technology to meet industrial requirements, the Laboratory now provides a multitude of advantages in various fields, such as the ability to spot-cool high heat flux regions, enhance macro-level performance by optimization of micro-level heat transfer, and enable system-level miniaturization and integration.

  • Dr. Ohadi Publishes Book Chapter on Free Air Cooling

    Dr. Jun Dai, Prof. Michael Ohadi, and Prof. Michael Pecht have recently published a chapter titled, “Energy Efficiency and Reliability Risk Mitigation of Data Centers through Prognostics and Health Management,” in the book Cooling of Microelectronic and Nanoelectronic Equipment (WSPC Series in Advanced Integration & Packaging, Vol. 3). This book presents recent advances and emerging research from various experts in the field. Cooling systems account for a large share of energy consumption in data centers. One method that reduces energy consumption of data centers is known as free air cooling, where ambient air is used to cool equipment directly, thereby reducing the energy consumed for cooling and conditioning. This chapter presents an analysis of the potential risks arising from free air cooling based on the expected operating conditions. A prognostics-based approach to assess and mitigate… more>>

  • Dr. Ohadi awarded USM Regents’ Award for Innovation Excellence.

    Department of Mechanical Engineering Professor Michael Ohadi was selected as a recipient of a 2014 University System of Maryland (USM) Regents’ Faculty Award for Excellence in Innovation by the USM Board of Regents. This award is the highest honor that the Board bestows in recognition of exemplary faculty achievement. Ohadi is a founding faculty member of the University of Maryland’s (UMD) Center for Environmental Energy Engineering and has close to 20 years of industrial and academic experience in the areas of heat transfer, fluid flow, thermal energy conversion and electrohydrodynamics. Ohadi currently heads a team funded by a $2.1 million contract from the Defense Advanced Research Projects Agency’s (DARPA) Intrachip/Interchip Enhanced Cooling (ICECool) Program to develop “embedded cooling” technology for compound semiconductor microchips and high power electronic systems. His team will use an innovative two-phase… more>>

  • ASME Advanced Energy Systems Division 2013 Best Paper

    A UMD team led by Department of Mechanical Engineering Professor Michael Ohadi won the 2013 American Society of Mechanical Engineers (ASME) Advanced Energy Systems Division (AESD) Best Paper Award for their paper titled, “ESFuelCell2013-18394 Experimental Investigation of Advanced Microscale Reactors For Enhanced Carbon Capture And Natural Gas Sweetening Applications.” The team included Ph.D. graduate student Harish Ganapathy, Assistant Research Scientist Amir Shooshtari, Senior Research Scientist and Associate Research Professor Serguei Dessiatoun and Dr. Mohammed Alshehhi, an assistant professor in the mechanical engineering department at the Petroleum Institute in Abu Dhabi, United Arab Emirates. The team’s paper was based on research Ganapathy performed as part of his Ph.D. thesis. “Our pioneering work in mass transfer application of micro surfaces and fluidics has received much attention recently, evidenced from the number of citations received for our publications… more>>
