The present paper investigates the dynamic behaviors of a bubble restricted by two parallel plates near an elliptical wall. typical experimental phenomena are recorded employing high-speed photography and theoretical Kelvin impulse model is established. impacts spatial position curvature wall on collapse quantitatively investigated through verified against results. intensity direction during process compared discussed for different elliptical-shaped walls. main conclusions include: (1)...
Abstract During the spin-no-load mode, vibrational performance of reversible pump turbine is an important criterion for evaluation operational performances power station. In present paper, influences rotational speed variations on whole unit (including top cover, upper, and lower brackets) are experimentally investigated with discussions their sources propagation characteristics. According to levels dominant frequencies vibration signals obtained at cases different speeds could be divided...
In fluid machinery, the concurrent presence of cavitation bubbles and particle clusters leads to considerably damage material surfaces. This study investigates dynamics a bubble situated among triple particles based on Kelvin impulse model high-frame-rate photography, focusing impact dimensionless distance size. Specifically, jet, motion, interface evolution characteristics are quantitatively evaluated. The following conclusions obtained: (1) collapse shapes can be divided into three typical...
In the present paper, influences of load variations on pressure fluctuations especially in vaneless space a prototype reversible pump turbine are experimentally investigated generating mode. Original data obtained through on-site measurement further analyzed both time and frequency domains order to show propagation mechanism fluctuations. Our work reveals that dominant characteristic is blade passing (BPF, f*=1) between 52% 90% partial loads its harmonics (f*=2) 100% rated power,...
As wind power develops by leaps and bounds, its uncertainty has posed huge challenges for operational planning integrated electricity-gas system (IEGS). An approach based on affine arithmetic (AA) optimal power-gas flow (OPGF) considering of is proposed. Based convex envelope, AA-based OPGF model developed without non-affine operations. Uncertain treated form keeping track relationships between uncertain variables. By introducing AA theory, can be converted into deterministic multi-objective...
We try to predict the stock market using GAN model, which includes discriminator and generator. use MLP as predictor of uses Backpropagation. Besides, we Simon function monitor study model. Using have gotten graph three different companies in our paragraph. In addition, model figure know compare error with it is. Finally, formula calculate RMSE.
