Jiyu Wu

Principal Research Scientist

Jiyu Wu joined NPL in September 2006 as a Higher Research Scientist and became a Principal Research Scientist in April 2018. She is a lead scientist in the development of UK national standard thermal conductivity measurement facilities, in particular at high temperatures. She is responsible for the development of thermal conductivity reference materials for metals/alloys conforming to ISO Guide 34, which provide traceability of thermal conductivity data used in UK industry and worldwide. She led a multi-million Euro Joint Research Project, EMRP Thermo. Jiyu has been a member of the Institution of Mechanical Engineers (IMechE), and a Chartered Engineer since 2014. Jiyu is the Convenor of the CEN TC89/WG14 that is responsible for the thermal conductivity measurement standard for high temperature insulation. She also represents NPL at the EURAMET TC-T-Thermophysical Quantities of Materials Working Group and also participates as expert in the BIPM CCT-TG-ThQ that is in charge of thermophysical properties.

Areas of interest

Her work in the field of Thermal Science covers the following three areas:

  • High-temperature thermal conductivity measurements (National Physical Laboratory, UK)
  • Effect of adsorption on the surface tension of solids (University of Toronto, Canada)
  • High-temperature primary standard (National Institute of Metrology, China)

Currently, Jiyu is leading a UK National Measurement Office funded project “Multi-scale thermophysical characterisation for thin and complex layered materials”.

She is also the technical leader of the Work Package 4 of a EMPIR funded Joint Research Project, Hi-TRACE, and is working on the characterisation of thermal contact resistance.

She led an EMRP funded project, Thermo: Metrology for thermal protection materials (2013 – 2016). This is a Joint Research Project with other European National Measurement Institutes, LNE, PTB, MKEH and CMI. The summary of the project is published on the website of European Association of National Metrology Institutes (EURAMET), and it was co-funded by the UK National Measurement Office.
