Flow-injection of branched polymers inside nanopores

– Flexible chains (linear or branched) can be forced to enter into a narrow capillary by using a hydrodynamic flow. Here, we correct our earlier description of this problem by considering the progressive nature of the suction process. We find that the critical current for penetration, Jc, is controlled by the entry of a single blob of the capillary size, and that its scaling structure is the sa...

Branched Polymers

Intended as models in chemistry or biology, branched polymers are often modeled, in turn, by lattice animals (trees on a grid); see, e.g., [3, 5, 8, 10, 18, 19]. However, continuum polymers turn out to be in some respects more tractable than their grid cousins. In order to study the behavior of branched polymers, and in particular to define and understand what random examples look like, we must...

Collapse of branched polymers

2014 Exact calculations using transfer matrices on finite strips are performed to study the two-dimensional problem of one lattice animal with an attractive nearest neighbour interaction. Thermodynamic quantities such as specific heat, compressibility, thermal expansion are calculated. Finite size scaling with two strips of different widths yields very accurate approximations of the critical li...

Conformation of branched polymers

2014 We study the conformation of randomly branched, monodispersed polymers both in dilute and concentrated solutions in their reaction bath. We first extend the Zimm-Stockmayer mean field theory to such properties as elasticity and concentration correlations. We then take this mean field theory as a basis for a Flory approach. In a dilute solution, we recover previous results by Isaacson and L...

Influence of nozzle geometry and injection conditions on the cavitation flow inside a diesel injector

Cavitation and turbulence in a diesel injector nozzle has a great effect on the development and primary breakup of spray. However, the mechanism of the cavitation flow inside the nozzle and its influence on spray characteristics have not been clearly known yet because of the internal nozzle flow complexities. In this paper, a comprehensive numerical simulation is carried out to study the intern...
