[3] University of Manchester, Manchester, United Kingdom

The boundary layer flow above an isothermal flat plate inclined at a small angle to the horizontal is analyzed. Inclination effects are initially investigated as a perturbation to the horizontal flow by obtaining a fourth order series solutions valid near the leading edge of the plate ... Read More

Si-Infiltrated SiC Lattices in Elevated Temperatures: A Thermo-Mechanical Analysis

E. Rezaei [1],
[1] EPFL, Lugano, Switzerland

Si-infiltrated SiC porous composites exist in different forms composed of cores of cellular ceramic and skin plates of ceramic matrix composites. Due to high thermal conductivity, low coefficient of thermal expansion, high elastic modulus and high strength, the final product can be a ... Read More

Thermal and Laminar-Fluidic Workbench for a metric Portion of a Gun

M. Brun
Nexter Systems, Versailles, France

Part of a 120mm gun has been represented as a perforated conic iron solid, surrounded by an annular screen. Inside the gun are limit conditions of isolation or thermal flux. The screen is described as a shell, receiving solar heat and exchanging with the outside atmosphere. It bears a ... Read More

Numerical Study of Hyporheic Flow across Bedforms of Different Type

C. Gualtieri [1],
[1] University of Napoli Federico II, Department of Civil, Architectural and Environmental Engineering (DICEA), Napoli, Italy

Despite the traditional separation between the studies of surface water and groundwater flows, it has been long recognized that rivers and aquifers are strongly connected and that their interaction gives rise to a continuous exchange of water and solutes. The volume within the porous ... Read More

The Simulation of Flow and Reduction of NO in a Heterogeneous Reactor.

O. Śliczniuk [1], B. Olejnik [1],
[1] Wrocław University of Technology, Faculty of Chemistry, Department of Chemical Engineering, Wrocław, Poland

Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for ... Read More

熔喷是工业上用于制备微米纤维非织造布的一种工艺方法。在熔喷过程中,高聚物熔体经过高速、高温气流的拉伸,在接受装置上固化结晶形成微米纤维非织造布。由于熔喷材料具有很高的比表面积,因而具备良好的过滤性、吸附性、隔离性,可用于过滤材料、隔离材料、吸纳材料、口罩材料等领域。熔喷材料的优异性能是基于熔喷纤维的微纳米级的尺度,降低纤维的直径有利于提高熔喷产品的性能。由于纤维的拉伸细化发生在气流场的运动过程中,因此对纤维运动的研究具有重要意义。本研究将高聚物与气流所形成的混合体系作为两相流来处理。我们采用Comsol multiphysics 的水平集方法对熔喷过程的高聚物 ... Read More
