Dr.Zhang Jintao


Curriculum Vitae

Dr. Zhang Jintao got his Ph.D. in Thermal Physics from Tsinghua University in 2000 and continued his Post Doctoral Associate in Renssalaer Polytechnic Institute from 2000 to 2001. His study interest at that time was focused on phase change and transport dynamics through interfaces of liquid thin films.

Since 2001, he has worked for National Institute of Metrology (NIM), China. He focused his academic interests in fundamentals of thermometry. He led the project of redetermination of Boltzmann constant in NIM and advanced in the novel method of fixed-path-length cylindrical cavity. Apart from that, with NIM colleagues he extended his study to primary thermodynamic temperature measurements by novel refractive index method and acoustic resonant method and accurate measurements of thermal properties of fluids. He then devoted himself to solving metrological problems in the measurements of thermal physical properties and monitoring of greenhouse gas emissions.

He was honored by the Academic Rookie Award of Tsinghua University (2000); Outstanding PhD Dissertation of Tsinghua University (2002); Outstanding Staff (2011) of the AQSIQ of P. R. China. He has authored 50 academic publications. He assigned as the representative of NIM in tTC12 of IMEKO, CCU and CCT of the CIPM, and some working groups of CCT.


Researches and Achievements

Dr. Zhang Jintao proposed a physical model to explain the explosive phase change mechanisms in microchannels in his PhD study (J.Microscale Thermophysics Engineering 4 177–89, 2000). After his joining in NIM, he focused his interest in fundamental metrological problems in thermometry and measurements of thermal physical properties. He pioneered the study of primary thermometry in NIM. He built a research group specialized in the studies of thermometry and measurements of fluid properties. He proposed a method of fixed-path-length cylindrical resonator for redetermination of Boltzmann constant kB. The uncertainty of the determination of kB reached around 2ppm which is one of the leading results in international thermometry community. Besides, he helped setting up bilateral collaborations in thermometry with EMRP organization and a number of world leading metrology laboratories of NIST, PTB, MSL, INRIM and NPL. He co-organized NIM/NIST GHG emission workshops twice. He currently extended his research interests in solving metrological problems energy saving and GHG emissions monitoring.
