The paper discusses the state of stress in a slowly-closing valve during accelerated start-up of a steam turbine. The valve is one of the first components affected by high temperature gradients and is a key element on which the power, efficiency and

The paper presents the results of a Thermal-FSI analysis of accelerated start-up of a turbine controlled by an additional injection of cooling steam. The work contains a description of the phenomena that occur during the start-up as well as the accom

The paper compares two strength hypotheses: the well-known Huber-Mises-Hencky, the Zawadzki hypothesis. The analysis was carried out on a steam turbine blade, which was thermally loaded. The results of the obtained stress values were compared for bot

The work discussed an extreme case of cooling a steam turbine. The ship’s steam turbine was used as an example. In marine transport units with low-speed engines dominate, however, there are also units with steam turbines. An example of analysed mar

It is known that nano- and micromechanics require new approaches to right describing of surface-like phenomena which lead to an enhanced energy conversion. In this work, a general form of surface forces that consist of a contribution from both the fr
