Quantification of large steam bubble oscillations and chugging using image analysis
(Lappeenranta-Lahti University of Technology LUT, 2019-11-01)
The pressure suppression pool of a boiling water reactor as a safety system has vital importance from the nuclear reactor safety point of view. If a loss-of-coolant accident occurs, a large amount of steam is pushed through ...
Supercritical CO2 Numerical Modelling and Turbomachinery Design
(Lappeenranta-Lahti University of Technology LUT, 2019-04-16)
Supercritical CO2 Brayton cycles have attracted significant attention in recent years on the basis that they can achieve higher thermal efficiency at relatively lower turbine inlet temperature in comparison to conventional ...
Agent-Based Modeling as Part of Biomass Supply System Research
(Lappeenranta-Lahti University of Technology LUT, 2019-06-14)
Interest in the use of agent-based modeling (ABM) for studying biomass supply systems has increased because of its flexible and cost-efficient nature. While ABM has been around for a long time, recent developments in ...
Improving the environmental safety of ash from bioenergy production plants
(Lappeenranta University of Technology, 2018-12-14)
Each year, energy production plants in Eastern Finland produce just under 100,000 tonnes of different types of ash and slag in the process of energy production. The utilisation of energy production ash flows has made ...
