Associate Professor

Arjan Frijns


Arjan Frijns is a dedicated researcher within the Energy Technology group at Eindhoven University of Technology (TU/e), specializing in the field of micro-thermo fluidics. His research primarily focuses on investigating heat and mass transfer phenomena within microfluidic and porous structures.

His primary areas of interest encompass fundamental studies on heat transfer at the nano- and micro-scales, evaporative cooling, and multi-scale modeling (MD, DSMC, hybrid MD-DSMC and CFD). To validate the models, he also conducts experimental research using micro-Particle Image Velocimetry (micro-PIV), 3D micro-Particle Tracking Velocimetry (micro-PTV), and other techniques. He has an extensive track record of collaborative projects with industry, e.g. on evaporative (micro-channel) cooling, on rarefied gas flows and on microfluidic sensors.

Furthermore, he is also interested in heat transfer modeling in the human body, in particular in relation to individual thermal sensation and thermal comfort in the built environment. In close collaboration with the Department of Human Biology at Maastricht University, he successfully developed the dynamic thermoregulation model ThermoSEM. This model combines neurophysiological mechanisms with internal heat transfer mechanisms to better understand and predict thermal responses in humans.


Arjan Frijns obtained his MSc in Mechanical Engineering and his PhD from the department of Mathematics at TU/e. After a post-doctoral position in the field of heat transfer, he was appointed as Assistant Professor in the Energy Technology group at the TU/e (department of Mechanical Engineering). He worked in 2005 as visiting scientist in the group of prof. Peter Stephan (Technische Universität Darmstadt) and in 2016 in the group of prof. Geert van Steenberge (Ghent University / IMEC). Since 2012 he is co-chair of the international conference series on Non-Equilibrium Gas Flows (NEGF).
