The helical cruciform fuel (HCF) is characterized by self-supporting and enhanced transverse mixing, which may replace the cylindrical fuel of the light water reactor (LWR). In this work, the flow resistance and phase distribution of a 4×4 HCF assembly was investigated by experimental method. The experimental system of air-water two-phase flow was established, and the void fraction was gained by wire-mesh sensor (WMS). The dummy HCF elements produced by additive manufacturing technology were assembled with the locating plates. The evolution of the flow regime and the void fraction of the central and peripheral were paid particular attention. The correlations for the two-phase friction multiplier and void fraction were proposed based on the experimental data. © 2024, The Authors. All rights reserved.

This paper presents a fast microwave near-field phase retrieval method based on an Improved Diffraction Neural Network (IDNN). The method first modifies the Rayleigh-Sommerfeld (RS) formula using the angular spectrum method to adapt it for the Phase Retrieval (PR) equation. By enhancing the output layer of the DNN to simultaneously provide amplitude and phase information and incorporating a backward phase iteration step, the accuracy of phase retrieval is significantly improved. The optimization process leverages a custom-designed loss function and the Adam optimizer for gradient descent, enabling the retrieval of phase information using only amplitude data from two plane measurements. Simulation results validate the effectiveness of this approach and demonstrate its advantages in speed compared to classical algorithms such as the Gerchberg-Saxton (GS) algorithm and the Truncated Amplitude Flow (TAF) algorithm. © 2024 IEEE.

The frequency mismatch effect in narrowband active power filtering process is analyzed and a solution to alleviate the effect is validated by simulation. The result shows the performance of harmonic suppression gets worse in presence of frequency mismatch but this effect can be compensated by applying a suitable step-size value of least-mean-square algorithm. © 2022 IEEE.

The electro-thermal characteristics of PIN diode under electromagnetic pulse signal are studied by simulation. The effects of temperature and electric field on the mobility and thermal conductivity of materials are considered in order to realize electro-thermal coupling analysis of PIN diode. The distribution of carriers, temperature and electric field inside the diode is obtained. The simulation results show that the peak electric field and temperature are concentrated near the P+ N- junction and N- N+ junction under electromagnetic pulse signal. The temperature increases faster with the increase of injection signal amplitude and the rising time of signal has little effect on rate of temperature rise inside PIN diode. The burn out time of diode is also affected by frequency of injected Sine signal. The simulation results are of great significance to the protection of PIN diode. © 2022 IEEE.

The main incentive to study cavitation inception has been the accompanying jump of noise. In this paper, the problem of tip leakage vortex cavitation inception is studied through experiments methods. The model tests of cavitation inception have been carried out at SSSRI K15 Cavitation Tunnel. From the perspective of the experimental results, it is instructive for engineering design. In a given blade tip working load, ie, the actual angle of attack and incoming flow are determined, the tip clearance vortex cavitation can be suppressed by further optimization of the gap between the blade and wall surface. © 2022 by the International Society of Offshore and Polar Engineers (ISOPE).

The adaptive active power filter based on LMS algorithm has limited compensation ability for the phase difference caused by the secondary channel, which makes its suppression function of harmonic current invalid, and may enhance the harmonics in serious cases. Based on time delay, this paper proposed a phase compensation method of secondary channel, which can effectively compensate the phase difference caused by secondary channel and realize the interference of any frequency point in the target frequency band. © 2022 IEEE.
