Abstract: A computer three-dimensional (3D) vision-aided performance prediction framework for turbomachinery is established in this paper, to improve the accuracy and generalization ability of the artificial neural network (ANN) ...

Abstract: In recent years, in order to achieve higher performance, the number of design variables used in the aerodynamic optimization of turbomachinery (based on surrogate models) has increased significantly. However, the increase ...

Abstract: Radiative cooling materials (RCMs) based on polymers, which reflect solar irradiance (0.24–2.5 μm) strongly and emit radiation within atmospheric window (8–13 μm) intensively, have yielded obvious cooling performance. ...

Abstract: A full-range prediction model for turbomachinery based on the flow-field information code is established in this article to solve the problems that traditional models do not have enough prediction accuracy and cannot reflect ...

Abstract: Recuperators with design temperatures at and above 800 °C can further increase the thermal efficiency of supercritical CO2 power cycles by enabling higher turbine exhaust temperatures. Mar-M247 is a well-suited nickel-based ...

Abstract: In recent years, we have made several improvements to the geometric parameterization method, the surrogate model method, and the sampling method, with the goal of making the traditional surrogate model-based optimization ...
