Polymer crystallization under external flow
Reports on Progress in Physics, 2022Abstract The general aspects of polymer crystallization under external flow, i.e., flow-induced crystallization (FIC) from fundamental theoretical background to multi-scale characterization and modeling results are presented. FIC is crucial for modern polymer processing, such as blowing, casting, and injection modeling, as two-third of ...

Study of transition location effect (from natural transition to fully turbulent) on separation size, shock structure and unsteadiness was the focus of this WP. Boundary layer tripping (by wire or roughness) and flow control devices (VG) were used for boundary layer transition induction.

External Flows and Development in Bolivia
SSRN Electronic Journal, 2013External resources for a low income country have the potential of accelerating growth but also of creating Dutch Disease effects. This paper analyses the empirical impact of the most important external resources, foreign direct investment, aid, and loans, on the Bolivian economy for the period 1950-2009.

Flow Decompositions in External Memory
2013Let G = (V,E) be a digraph with disjoint sets of sources S ⊂ V and sinks T ⊂ V endowed with an S–T flow f : E → ℤ + . It is a well-known fact that f decomposes into a sum ∑ st f st of s–t flows f st between all pairs of sources s ∈ S and sinks t ∈ T. In the usual RAM model, such a decomposition can be found in \(O(E \log \frac{V^2}{E})\) time.

The flow external to a rotating torus
Theoretical and Computational Fluid Dynamics, 2015Imparting a sudden rotation to a torus (or other symmetric smooth object) in an otherwise quiescent, viscous fluid serves to generate boundary layers at the object’s surface. These boundary layers are known to exhibit a finite-time singularity at the equator which manifests in a thickening of the boundary layer and subsequent development of an ...

External detection of axoplasmic flow using radionuclides
Neuroradiology, 1976In order to investigate the possibilities of studying the axoplasmic flow in vivo by means of radionuclide scanning 75Se-methionine was injected into the L6, L7 or S1 spinal ganglia of cats and the spread of the isotope recorded with a gamma camera. -2.

Effect of external shear flow on sperm motility
Soft Matter, 2019The trajectory of sperm in the presence of background flow is of utmost importance for the success of fertilization, as the sperm encounter background flow of different magnitude and direction on their way to the egg.

Unsteady vorticity–streamfunction algorithm for external flows
Computers & Fluids, 2000The authors describe the development of a combined finite difference/finite volume scheme using a non-orthogonal C-grid for numerical approximation of Reynolds-averaged Navier-Stokes equations. Thereby, a comparison is shown for the algebraic zero-equation model of Baldwin and Lomax, and for one-dimensional models of Baldwin and Barth and Spalart and ...
