Ultrasonic rolling strengthening theory and mechanism analysis of high-strength 42CrMo steel
(Elsevier, 2025-04-18)
Article
Open Access42CrMo steel is widely utilized in the manufacturing of high-speed, heavy-duty components due to its excellent wear resistance and hardness. To further enhance its performance and extend its service life, ultrasonic rolling ... -
Research on the applicability of hybrid RANS/LES models to predict the flow behavior in bulb tubular pump under rated and stall conditions
(John Wiley & sons, 2025-02-21)
Article
Open AccessThe investigation into the internal flow characteristics of the bulb tubular pump device has important practical significance for improving both optimal design and operation stability. This paper uses different RANS/LES ... -
Experimental identification of characteristic curves of supersonic vacuum ejector and empirical prediction of total evacuation time
(Multidisciplinary Digital Publishing Institute, 2025-02-01)
Article
Open AccessSupersonic vacuum generators, or ejectors, operate pneumatically to extract air from tanks in industrial applications. A key performance metric for ejectors is the Total Evacuation Time (TET), which measures the time ... -
Dynamic structural characteristics of rotor components during the start-up transition of the LFR main coolant pump
(2025-01-01)
Article
Open AccessThe delivery medium of the LFR main coolant pump (MCP) is lead-bismuth eutectic (LBE). During startup, the MCP's impeller encounters direct interaction forces with the high-density LBE, subjecting the rotor to substantial ... -
Study on evolution characteristics of energy dissipation and vortex in pump-turbine during load rejection transition process
(2025-02-03)
Article
Restricted access - publisher's policyThe widespread adoption of intermittent wind and solar energy sources disrupts the stability of power grids, necessitating frequent load rejection processes for pump-turbine. This jeopardizes the stability of pump-turbine ... -
Research on the mechanism of the effect of vortex on the hydraulic loss of pump as turbine units based on entropy production theory
(2025-02-01)
Article
Restricted access - publisher's policyPump as turbine (PAT) is a common method of energy recovery, however, vortices are a negative phenom for these units. The objective of this research is to study the effect of vortex motion on the hydraulic loss of pump as ... -
Experimental study on pressure fluctuation in header of nuclear power plant SEC system after long-term pump shutdown
(2024-09-01)
Article
Restricted access - publisher's policyThe Essential Service Water System (SEC) is a nuclear safety level system in nuclear power plants. It’s responsible for transporting the heat load collected by the equipment cooling water system (RRI) to the final heat ... -
Towards shock absorbing hyperelastic metamaterial design (II): a prospective multiscale buckling-lattice computational model
(Springer, 2025-01-23)
Article
Open AccessAs a continuation of a previous work of the authors, on Computational Design of Shock-absorbing Metamaterials (Part I) (NunezLabielle et al. in Comput Methods Appl Mech Eng 393:114732, 2022), this work explores the potential ... -
Large-scale horizontal axis wind turbine aerodynamic efficiency optimization using active flow control and synthetic jets
(Elsevier, 2025-03)
Article
Restricted access - publisher's policyEfficiency increase is seen as one of the main goals of any energy-converting device. In this direction, the present study aims to demonstrate that large-scale wind turbines can still be improved in order to generate larger ... -
A new dual steering system in a compact tractor
(Multidisciplinary Digital Publishing Institute (MDPI), 2025-01-17)
Article
Open AccessTo achieve optimal controllability in a dual steering tractor (a four-wheel, iso-diametric tractor equipped with a dual-hydraulic steering system), this study proposes a coordinated approach that combines experimental ... -
Numerical investigation on loading pattern of railway concrete slabs
(SAGE publishing, 2024-08-27)
Article
Open AccessDespite the recent surge in the construction of ballastless railway tracks, there exists a notable research gap concerning the rail seat load (RSL) associated with these track types. The RSL is the load transferred from ... -
Analysis of unsteady flow and interstage interference of pressure pulsation of two-stage pump as turbine under turbine model
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-11-01)
Article
Open AccessThe process pump as turbine (PPAT) serves as a crucial component for recovering high-pressure energy from mediums used in chemical and refining processes. Ensuring the long-term safe and stable operation of PPAT in ...
