Analysis of Heterogeneous Nucleation and Erosion Behavior Considering the Injection of Impurities into Wet Steam Flow Using Poly-dispersed Method

Amir Momeni Dolatabadi et al.

Summary: Solid salt injection in steam turbines can cause heterogeneous nucleation, leading to changes in turbine operation and power. This study calculates and considers the effects of heterogeneous nucleation by injecting NaCl into wet-steam flow parameters, erosion rate, and turbine power. Numerical results show a reduction in condensation shock, a decrease in erosion rate, and an increase in steam turbine power due to the presence of solid particles.

Bayesian texture optimization using deep neural network-based numerical material test

Ryunosuke Kamijyo et al.

Summary: This paper proposes a new computational method, named Bayesian texture optimization, for improving the formability of aluminum alloy sheets. The method achieves significant acceleration by using a deep neural network to estimate mechanical properties and adopting Bayesian optimization for handling a small number of trials. It is shown that Bayesian texture optimization can obtain a plastically isotropic aluminum alloy sheet and provides a framework for understanding other desirable textures and associated uncertainties in the solution space.

The best angle of hot steam injection holes in the 3D steam turbine blade cascade

Amir Kafaei et al.

Summary: In order to enhance the efficiency of steam turbines, injecting hot steam between the blades in a 3D manner was studied in this paper. The optimal angle for injection holes was found to be -60 degrees, resulting in reductions of 40% in liquid mass fraction, 22% in condensation loss, and 1% in kinetic energy. The economic cost was calculated at 0.56 ($/hour) with a hot steam injection hole size of 0.07.
