In water-lubricated pipeline transportation of heavy oil and bitumen, a thin oil film typically coats the pipe wall. A detailed study of the hydrodynamic effects of this fouling layer is critical to the design and operation of oil-water pipelines, as it can increase the pipeline pressure loss （and pumping power requirements） by 15 times or more. In this study, a parametric investigation of the hydrodynamic effects caused by the wall coating of viscous oil was conducted. A custom-built rectangular flow cell was used. A validated CFD-based procedure was used to determine the hydrodynamic roughness from the measured pressure losses. A similar procedure was followed for a set of pipe loop tests. The effects of the thickness of the oil coating layer, the oil viscosity, and water flow rate on the hydrodynamic roughness were evaluated. Oil viscosities from 3 to 21300 Pa s were tested. The results show that the equivalent hydrodynamic roughness produced by a wall coating layer of viscous oil is dependent on the coating thickness but essentially independent of oil viscosity. A new correlation was developed using these data to predict the hydrodynamic roughness for flow conditions in which a viscous oil coating is produced on the pipe wall.

We explored the influence of the artificial diets with different protein and glucose contents on larval development,fecundity and enzyme activities of the beet armyworm spodoptera exigua （Hübner）.Our results suggested that development,fecundity and population growth index of beet armyworm increased with increased nutritional content in the artificial diets;however,when the yeast to cellulose content ratio reached 46.8：53.2,the fecundity and population growth had reached a maximum and additional protein did not yield additional ***,3rd instar beet armyworm larvae fed on different artificial diets had increased enzymatic activities of acetylcholinesterase （AChE） with the increased nutritional content,but carboxylesterase （CarE） activities did not significantly change under variation in the nutritional content.

The main objective of this work is to predict the mixing of two different miscible oils in a very long channel. The background to this problem relates to the mixing of heavy and light oil in a pipeline. As a first step, a 2D channel with an aspect ratio of 250 is considered. The batch-mixing of two miscible crude oils with different viscosities and densities is modeled using an unsteady laminar model and unsteady RANs model available in the commercial CFD solver ANsYsFluent. For a comparison, a LEs model was used for a 3D version of the 2D channel. The distinguishing feature of this work is the Lagrangian coordinate system utilized to set no-slip wall boundary conditions. The global CFD model has been validated against classical analytical solutions. Excellent agreement has been achieved. simulations were carried out for a Reynolds number of 6300(calculated using light oil properties) and a schmidt number of 10~4. The results show that, in contrast to the unsteady RANs model, the LEs and unsteady laminar models produce comparable mixing dynamics for two oils in the channel. Analysis of simulations also shows that, for a channel length of 100 m and a height of 0.4 m, the complete mixing of two oils across the channel has not been achieved. We showed that the mixing zone consists of the three different mixing sub-zones, which have been identified using the averaged mass fraction of the heavy oil along the flow direction. The first sub-zone corresponds to the main front propagation area with a length of several heights of the channel. The second and third sub-zones are characterized by so-called shear-flow-driven mixing due to the Kelvin–Helmholtz vortices occurring between oils in the axial direction. It was observed that the third sub-zone has a steeper mass fraction gradient of the heavy oil in the axial direction in comparison with the second sub-zone, which corresponds to the flow-averaged mass fraction of 0.5 for the heavy oil.

Remediation into film of the Danish author Hans Christian Andersen＇s many fairytales often accentuate his quaint or sentimental tendencies. In a silent film adaptation of ＂The Little Match Girl＂ the French filmmaker Jean Renoir transports us into an avant-garde world of consumerism and commodification that seems at odds with Andersen＇s original vision. Yet Renoir＇s film is remarkably resonant with Andersen＇s own pre-cinematic imagination even as it produces a different inflection of the uncanny. The match girl is turned into a femme enfant fatale and her illu- minated visions are redirected away from the comforts of home to a world of artifice and melodrama.
