Teemu Turunen-Saaresti

Teemu Turunen-Saaresti is a Tenured Professor at the School of Energy Systems, LUT University, Lappeenranta, Finland. His research focuses on energy technology, particularly supercritical CO2 cycles, Organic Rankine Cycles (ORC), turbomachinery, and heat pump design.

• PhD in Energy and Environmental Technology (2004), Lappeenranta University of Technology
• MSc in Energy and Environmental Technology (2001), Lappeenranta University of Technology

His work spans Supercritical CO2 Power Cycles, Organic Rankine Cycle Systems, Turbomachinery Design, and Non-Equilibrium Condensation Modeling. Recent studies include printed circuit heat exchangers for transcritical cycles, high-temperature ORC thermal inertia, and centrifugal compressor design for large-scale CO2 heat pumps.

Publications highlight trends in sCO2 Turbines, Tip Clearance Effects, and Multiphase Flow Simulation. Funding from the Academy of Finland and Business Finland supports his research on computational/experimental condensing flows, small-scale compressors, and green shipping energy solutions.

He collaborates with international teams on projects like the International Wet Steam Modeling Project, contributing to guidelines for high-temperature heat pumps (IEA HPT Annex 58) and advancements in hydrogen compression strategies.
