The dynamic behaviours of a filament in viscoelastic uniform flow were investigated by an immersed boundary-lattice Boltzmann method. effects the Reynolds numbers (Re, ranging from 10 to 200) and Weissenberg number (Wi, 0 1.2) on flapping motion drag lift coefficients studied. It was found that higher inertial effect (larger Re) promotes filament. In addition, major viscoelasticity Giesekus flu...

Okul öncesi fen eğitiminde temalı bilgi veren resimli çocuk kitapları, bilimsel bilgilerin kazandırılmasında ve süreç becerilerinin geliştirilmesinde oldukça önemlidir. Ulusal uluslararası alan yazında yapılmış olan araştırmalar okul öğretmenlerinin fene karşı ön yargılı düşük öz-yeterlik inancına sahip olduklarını, kavram bilgilerinin yeterli düzeyde olmadığını göstermektedir. Bu noktada dönem...

We study the flow around a periodic array of cylinders using mesoscopic viscoelastic fluid that mimics polymeric solutions. model our employing novel method based on Smoothed Dissipative Particle Dynamics and FENE springs. characterize static dynamic properties solutions compare results with theoretical predictions Zimm model. After rheological characterization modeled solutions, we simulate co...

We study the existence of global-in-time weak solutions to a coupled microscopicmacroscopic bead-spring model which arises from the kinetic theory of dilute solutions of polymeric liquids with noninteracting polymer chains. The model consists of the unsteady incompressible Navier–Stokes equations in a bounded domain Ω ⊂ Rd, d = 2 or 3, for the velocity and the pressure of the fluid, with an ela...

In this paper it is presented the use of P systems and π-calculus to model interacting molecular entities and how they are translated into a probabilistic and symbolic model checker called PRISM.
