Optimizing the desired properties for stretch monolayer separators used in Lithium-ion batteries has been a challenge. In the present study a cellulose nanofiber/PET nonwoven composite separator is successfully fabricated, using a wet-laid nonwoven (papermaking) process, which can attain optimal properties in wettability, mechanical strength, thermal resistance, and electrochemical performance ...

The separation efficiency and pressure drop of the dynamic separator cement particles can be affected by many factors, like structural type, geometric parameters, operating characteristics. In this paper, CFD modeling is applied to investigate fluid flow behavior industrial with different heights inner cone called vortex breaker. Simulations are based on RSM DPM models. A comparison original de...

We show that the formation of a vortex lattice in a weakly interacting Bose condensed gas can be modeled with the nonlinear Schrödinger equation for both T=0 and finite temperatures without the need for an explicit damping term. Applying a weak rotating anisotropic harmonic potential, we find numerically that the turbulent dynamics of the field produces an effective dissipation of the vortex mo...

We present a finite energy topological Z(2) vortex solution in a 2 + 1 dimensional SO(3) gauge field theory minimally coupled to a matrix valued Higgs field. The vortex carries a Z(2) magnetic charge and obeys a modulo two addition property. The core of this vortex has a structure similar to that of the Abrikosov vortex appearing in a type II superconductor. The implications of this solution fo...

Cephalopods, among other marine animals, use jet propulsion for swimming. A simple actuator is designed to loosely mimic pulsatile jet formation in squid and jellyfish. The actuator is comprised of a cavity with an oscillating diaphragm and an exit orifice. Periodic oscillation of the diaphragm results in the formation of an array of vortex rings and eventually could generate a periodic pulsati...

We develop a stochastic Gross-Pitaveskii theory suitable for the study of Bose-Einstein condensation in a rotating dilute Bose gas. The theory is used to model the dynamical and equilibrium properties of a rapidly rotating Bose gas quenched through the critical point for condensation, as in the experiment of Haljan et al. #Phys. Rev. Lett. 87, 210403 !2001"$. In contrast to stirring a vortex-fr...

In this research, inorganic material type and content influence on coating of commercially available polypropylene (PP) separator were studied for improving its performance and safety as lithium ion battery separator. Heat-resistant nanopowders of Al2O3, SiO2 and ZrO2 were coated using polyvinylidene fluoride (PVDF) binder. Coating effects on the separators morphology, wettability, high tempera...

Currently, computational fluid dynamics has become the primary method for analyzing flow state inside machine. Herein, Ansys Fluent software is used to design a more effective oil-field device, namely, gas–liquid cylindrical cyclone (GLCC)-horizontal combined separator. The characteristics of mixed flow, turbulence intensity, and phase volume fraction distribution are analyzed, factors affectin...
