DC Circuit Breaker Evolution, Design, and Analysis.

Publication Type: Academic Journal

Source(s): Energies (19961073). Sep2023, Vol. 16 Issue 17, p6130. 16p.

Abstract: While traditional AC mechanical circuit breakers can protect AC circuits, many other DC power distribution technologies, such as DC microgrids (MGs), yield superior disruption performance, e.g., faster and more reliable switching speeds. However, novel...

The Optimization, Kinetics Model, and Lab-Scale Assessments of Phenol Biodegradation Using Batch and Continuous Culture Systems.

Publication Type: Academic Journal

Source(s): Sustainability (2071-1050). Aug2023, Vol. 15 Issue 16, p12405. 20p.

Abstract: Phenol was considered a severe hazard to all ecosystems even at low concentrations. The bioremediation process is an eco-friendly process for complete phenol degradation and bioelectricity generation. In the present study, a consortium of native isolat...

Influence of the Type of Receiver on Electrical Energy Losses in Power Grids.

Publication Type: Academic Journal

Source(s): Energies (19961073). Aug2023, Vol. 16 Issue 15, p5660. 22p.

Abstract: The development of power electronics, including high-efficiency power supply systems, changes the structure of perception of the types of electrical energy receivers connected to the power grid at each supply voltage level. In the past, the dominant ty...

Analysis of the Energy Loss Mechanism of Pump-Turbines with Splitter Blades under Different Characteristic Heads.

Publication Type: Academic Journal

Source(s): Water (20734441). Aug2023, Vol. 15 Issue 15, p2776. 22p.

Abstract: The operating efficiency of high-head pump turbines is closely related to the internal hydraulic losses within the system. Conventional methods for calculating hydraulic losses based on pressure differences often lack detailed information on their dist...

Study on the Energy Loss Characteristics of Shaft Tubular Pump Device under Stall Conditions Based on the Entropy Production Method.

Publication Type: Academic Journal

Source(s): Journal of Marine Science & Engineering. Aug2023, Vol. 11 Issue 8, p1512. 17p.

Abstract: This study aimed to reveal the energy loss characteristics of each part of the shaft tubular pump device (STPD) under stall conditions. Numerical simulations were conducted by using the SST k-ω turbulence model with curvature correction, and the reliab...

Sill Role Effect on the Flow Characteristics (Experimental and Regression Model Analytical).

Publication Type: Academic Journal

Source(s): Fluids. Aug2023, Vol. 8 Issue 8, p235. 18p.

Abstract: This study investigates the effects of gate openings and different sill widths on the sluice gate's energy dissipation and discharge coefficient (Cd). The physical model of the sills includes rectangular sills of different dimensions. The results show ...

Discussion on Calculation Method of Magnification Factor of Toggle-Brace-Viscous Damper.

Publication Type: Academic Journal

Source(s): Buildings (2075-5309). Aug2023, Vol. 13 Issue 8, p2006. 17p.

Abstract: At present, dampers are widely used in the field of energy dissipation in engineering structures. However, when the displacement and velocity output of dampers are not significant under small and medium-sized earthquakes, it is difficult for a damper t...

Experimental Investigation of Precast Rocking Walls Incorporating Tension-Compression and Shear Steel Energy Dissipaters.

Publication Type: Academic Journal

Abstract: To fully utilize the potential of earthquake-resistance capacity in rocking wall systems and improve repairability after earthquakes, a precast rocking wall structure is developed with the installation of multiple steel energy dissipaters, i.e., tensio...

A Simple Model for Wake-Induced Aerodynamic Interaction of Wind Turbines.

Publication Type: Academic Journal

Source(s): Energies (19961073). Aug2023, Vol. 16 Issue 15, p5710. 13p.

Abstract: Wind turbine aerodynamic interactions within wind farms lead to significant energy losses. Optimizing the flow between turbines presents a promising solution to mitigate these losses. While analytical models offer a fundamental approach to understandin...

Numerical investigation of nonlinear radiative flux of non-Newtonian MHD fluid induced by nonlinear driven multi-physical curved mechanism with variable magnetic field.

Publication Type: Academic Journal

Source(s): Journal of Nigerian Society of Physical Sciences. Aug2023, Vol. 5 Issue 3, p1-11. 11p.

Abstract: This paper discusses two-dimensional heat flow of an incompressible non-Newtonian hydromagnetic fluid over a power-law stretching curved sheet. The energy equation of the flow problem considers a radiative flux influenced by viscous dissipation and sur...
