Grönman, Aki; Nerg, Janne; Sikanen, Eerik; Sillanpää, Teemu; Nevaranta, Niko; Scherman, Eero; Uusitalo, Antti; Uzhegov, Nikita; Smirnov, Alexander; Honkatukia, Juha; Sallinen, Petri; Jastrzebski, Rafal; Heikkinen, Janne; Backman, Jari; Pyrhönen, Juha; Pyrhönen, Olli; Sopanen, Jussi; Turunen-Saaresti, Teemu (Elsevier, 11.09.2020)Many waste heat recovery and biomass applications offer opportunities for small-scale steam turbines to produce electricity and to improve systems’ energy efficiency. However, the currently used axial turbine-based technology ... -
Experimental study of small scale and high expansion ratio ORC for recovering high temperature waste heat
Uusitalo, Antti; Turunen-Saaresti, Teemu; Honkatukia, Juha; Dhanasegaran, Radheesh (Elsevier, 11.07.2020)In recent times, the use and development of small-scale ( 10 kW) ORC systems has received an increasing interest. However, the operational characteristics of small-scale high-expansion ratio ORC turbines are not yet well ... -
Numerical analysis of working fluids for large scale centrifugal compressor driven cascade heat pumps upgrading waste heat
Uusitalo, Antti; Turunen-Saaresti, Teemu; Honkatukia, Juha; Tiainen, Jonna; Jaatinen-Värri, Ahti (Elsevier, 14.05.2020)Heat pump technology has the capability to upgrade unusable low-temperature waste heat and make the upgraded heat usable for different types of industrial and domestic heating applications. Heat upgrading could allow to ... -
Validation of the Axial Thrust Estimation Method for Radial Turbomachines
Tiainen, Jonna; Jaatinen-Värri, Ahti; Grönman, Aki; Sallinen, Petri; Honkatukia, Juha; Hartikainen, Toni (Hindawi, 24.02.2021)The fast preliminary design and safe operation of turbomachines require a simple and accurate prediction of axial thrust. An underestimation of these forces may result in undersized bearings that can easily overload and ...
