Research Fields and Orientations

The Center’s primary orientation is establishing high intensity heat transfer (hot-press transform and phase change heat transfer) and micro thermal physics research, with primary applications being high efficiency cooling (thermal management), waste heat utilization and thermal physical measurement.

Scientific research instruments and equipment

A hot wind tunnel simulating experimental device (under 1300℃) was designed and processed, and the Improvements on the dual wavelength of the femto-second laser pump probe system were completed, as were accurate measurements of solid-liquid interface thermal resistance. A micro liquid film measurement experimental apparatus has also been built. A variety of LED radiators and lighting products were also developed.

Major Achievements of 2014

Based on the femto-second laser pump probe experiment system, the Heat and Mass Transfer Research Center and University of Notre Dame developed a measurement system for measuring thermal conductivity of solid-liquid interfaces. This system had been applied in measuring the thermal conductivity of various solid-liquid interfaces successfully. The mechanism was investigated by using molecular dynamics simulation methods and thermal transport performance in solid-liquid interfaces controlled by experimental methodology. The thermal conductivity of the aurum-hexadecane interface increased from 28 MW/m²K to 169 MW/m²K. Results were published in a top journal: Advanced Materials (IF=15.409).

The project commissioned by China Electric Power Construction Group, ‘Concrete aggregate pre-cooling/preheat dynamic research and software development’, was completed. The research results filled the niche given the lack of systemic, effective and reliable design and calculation methods in water-power engineering, met the requirements for rapid and accurate engineering design, and proposed many methods for optimization. These results have far-reaching significance for the economic benefit and social benefit of water conservation and hydropower engineering. All evaluation experts recommended this project as an outstanding scientific research project of Chinese Electric Power Construction Group.

Organization and Personnel

At present the Center has 22 employees, including 2 researchers, 8 associate researchers, and 12 assistant researchers. There are 11 students including 6 doctors and 5 masters.

The Center’s dean Dawei TANG became a project evaluation expert of the China Aerospace Science and Technology Corp. He was elected director of Chinese Engineering Thermal Physics Institute at the 2014 Annual Engineering Thermophysics Conference. He was also recommended as the dean of the National Electronic Heat Conduction Material Standardization Technical Committee (in process).

Transfer and Industrialization of Technological Achievements

The Center won a total of 15 projects in 2014. 3 basic research projects were funded by the National Natural Science Foundations, including 2 general projects and 1 Youth project. The director’s fund funded 1 project, 9 projects were enterprise-commissioned, and 2 were joint projects of CAS and local governments. These contracts totaled 26M CNY. In 2014, about 12M CNY of funding was in place.

Patents and paper

In 2014, 56 papers were published, including 25 indexed by SCI and 34 by EI. 1 chapter of an English monograph and 1 chapter of a Chinese monograph were published. 1 international patent, 12 national invention patents and 3 utility model patents were applied for, and 8 national invention patents were granted.

The wettability of hexadecane on a metal surface was improved by the preparation of two kinds of SAM. The measurement results showed that thermal conductivity of the interface had good hexadecane wettability, and was far higher than that of interfaces with poor hexadecane wettability. This was because the interface with good wettability demonstrated much stronger intermolecular forces. Results were published in a top journal: Advanced Materials (IF=15.409).

International Cooperation and Exchanges

The Center established relationships with CU, ND, Aachen, Tokyo University and NIMS, gave a keynote address at the International Conference on the Phonon and Thermal Energy, and was elected as secretary-general of IHTC-16 and international committee member of ATPC.
