Effect of rotor area covered by end cover on flow characteristics and performance of seawater desalination energy recovery device

, 2020
The multi-phase flow mixing numerical model was used to simulate the influence of the end cover on the rotor area on the flow characteristics and performance of the seawater desalination energy recovery device under three structural designs. The pressure

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

Preparation and Performance Evaluation of a Self‐Generated Particle Plugging Agent Based on Thermosetting Resin

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.

Inertia Support Strategy for Wind Turbine Based on Switched Operating Points With Equivalent Time Constant

IEEE Access
The wind Turbine adopts Virtual Synchronous Generator (VSG) control to support grid frequency by releasing their energy reserve. However, the interaction between the maximum power point tracking (MPPT) control and VSG control will weaken their inertia ...

Experimental Study on the Enhancement of Heat Transfer Performance in Sintered‐Core Heat Pipes Using CuO Nanofluid

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents the design and construction of an experimental system for evaluating the thermal performance of heat pipes, using sintered‐wick heat pipes charged with CuO nanofluids. The device used in this study is a sintered‐wick heat pipe, in which the liquid return is driven by capillary forces within the porous wick structure.

Influence Mechanism of Structural Parameters of a Novel Sleeve‐Shaft Counterrotating Hydrodynamic Cavitation Reactor on Cavitation Characteristics and Performance

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study systematically investigates the cavitation characteristics of a novel sleeve‐shaft counterrotating (SSCR) hydrodynamic cavitation reactor using computational fluid dynamics (CFD). Based on the RANS framework combined with the SST k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model, the temporal–spatial evolution of ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics
