摘要 ：
Rotary energy recovery devices (RERDs) play a significant role in reducing the consumption of energy used in the desalination of seawater by reverse osmosis (SWRO). An integrated energy recovery and pressure boost device (IERPBD) applied to the recovery of hydraulic energy from the concentrated brine and pressurizes synchronously the seawater is introduced. To address the complex motion of the multiple lubricating gaps in IERPBD, especially piston ball/slipper and slipper/swashplate interfaces, an innovative computational fluid dynamics (CFD) model based on User Defined Function (UDF) is originally proposed. The characteristics of pressure, flow and mixing are analyzed to reveal the influence of multiple lubricating gaps leakage and mixing on energy recovery process. In addition, a SWRO system is built to investigate the effect of operating parameters and seawater salinities on the energy recovery and mixing properties of the IERPBD, and its structural parameters are optimized by parametric study, which further reveals the comprehensive characteristics of the IERPBD. The results indicate that the proposed CFD methodology can precisely analyze the energy loss and mixing properties of RERDs, and the utilization of IERPBD can diminish 25.7% of the energy consumption of SWRO system with 24.2% freshwater recovery ratio and 10 m(3)/d freshwater production.

摘要 ：
Cermets have been widely used in industry to combat wear and erosion because of their elevated strength and hardness and good wear resistance. This study investigated the tribological properties of WC-6Ni (YN6X), WC-6Co (YG6X), and WC-TiC-Co-Ni (TiCN) cermets during sliding over silicon carbide (SiC) in prepared seawater. Tribological experiments of 440C and GCr15 steel coupled with SiC were conducted for comparison. The influence of sliding speed was examined by multiple sequential increases in speed from 0.1 to 0.4 m s(-1). The results showed that the tribological properties of the tribopairs were enhanced with growing sliding speed and were influenced by complex factors including material hardness, wear radius, the lubricating medium environment, and the tribochemical reaction. YN6X performed particularly well due to its high hardness and presence of Ni which effectively reduced the corrosion effect of seawater. However, YG6X showed better wear resistance relative to YN6X in tap water due to its higher hardness. In particular, through an investigation of the wear process of the tribopairs in seawater, this study proposed the coefficient of friction model for cermet/SiC. The results indicated that a combination of YN6X/SiC has excellent potential for application to seawater hydraulic components.

摘要 ：
Accelerated life testing (ALT) and accelerated degradation testing (ADT) are two widely used accelerated testing (AT) methods for reliability evaluation of highly reliable products. However, in many cases, it is difficult to meet the estimation requirements only using ALT or ADT because of the nature of data and the test constraints. Since both ALT and ADT data provide useful reliability information, it would be quite valuable to use both of them for reliability estimation. In this paper, an optimal testing plan is proposed for the first time for such a hybrid AT under several experimental design constraints. An Inverse Gaussian (IG) process and the corresponding lifetime distribution are used to model the degradation process and the lifetime of the product, respectively. The strategy of allocating the test units to ALT and ADT and determining the data collection strategy in the experiment are presented. The objective is to maximize the estimation precision of the p-quantile of the product's lifetime under the normal use condition. A study on the stress relaxation of a type of electrical connector is conducted to illustrate the value of the proposed method in practice. © 2021 Elsevier Ltd

摘要 ：
The mechanism of the self-excited oscillation pulsed jet is still in a period of continuous improvement, and the application breadth and depth of the self-excited oscillation nozzle are significantly limited since the turbulent flow field inside the self-excited oscillation nozzle is exceptionally complex. In this study, computational fluid dynamics numerical simulation and experimental research methods are combined. By changing the structural parameters of self-excited oscillating nozzles, the velocity and pressure characteristics of the self-excited oscillating nozzles were compared and analyzed to determine the important factors that influenced the effect of pulsed jet. These findings demonstrated that the periodic expansion and contraction of the low-pressure vortex ring in the self-excited oscillation nozzle chamber will cause the pressure of the nozzle outlet section to change periodically. The periodic high-voltage blocking and low-pressure speedup of the outlet directly correlate with the pulsed jet. This study shows the reasonable size design range of the self-excited oscillation nozzle, which can guide the design and practical application of the nozzle, as well as provide the theoretical basis for perfecting the self-excited oscillation pulsed jet theory. © 2020, The Brazilian Society of Mechanical Sciences and Engineering.

摘要 ：
Abstract Seawater hydraulic axial piston pump (SHAPP) is a critical power component in underwater operating systems. A parameterized elasto-hydrodynamic (EHD) lubrication model of the piston/cylinder tribopair in the SHAPP is originally established, which considers the elasto-hydrodynamic behavior, viscosity temperature effect and deep-sea environmental pressure. The deformation of piston bush, bearing mechanism and energy loss characteristics of the water film under different operating conditions are discussed. The results show that the deformation of piston bush made of polyetheretherketone (PEEK) is in micron-scale under water film and deep-sea pressure, which could increase the leakage and viscous friction power loss of piston/cylinder tribopair. In deep-sea environment, the leakage and viscous friction power loss calculated by EHD are always greater than those calculated by hydrodynamic (HD), and increase with the increase of working pressure, shaft speed, gap size, sea depth and piston bush thickness. Besides, the increase of sea surface temperature could increase the leakage and decrease the viscous friction power loss of the piston/cylinder tribopair, respectively. Finally, design instructions to optimize the piston/cylinder tribopair are presented, therefore the proposed methodology can be used as a designing tool for SHAPP. © 2020 Elsevier Ltd

摘要 ：
Integrated rotary energy recovery-pressure boost device (IERPBD) is the essential component in seawater reverse osmosis (SWRO) desalination systems. And sliding bearing pair is the vital tribopair in the IERPBD, which guarantee the reliability of the device. However, the polyetheretherketone (PEEK) bearing in the IERPBD occurred early failure during the pre-experiment. To solve this problem, this paper firstly analyzed the reasons and mechanisms of sliding bearing early failure, which suggested that it was attributed to the low elasticity modulus and poor tribological performance of PEEK. Moreover, several improved "hard-to-hard" material combinations were proposed and screened through wear and friction experiments, and found that the WC-6Ni (YN6X)/silicon carbide (SiC) material combination has reasonable physicochemical properties and excellent tribological performance. Finally, the sliding bearing made of YN6X/SiC was equipped in IERPBD to carry out experiments under real working conditions to verify the performance of proposed material combination. The results indicated that YN6X/SiC sliding bearing pair could guarantee the continuous and stable operation of IERPBD, and effectively solve the sliding bearing failure problem.
