s In this study, Computational Fluid Dynamics (CFD) was used to simulate the flow and temperature distribution in zinc pot of hot-dip galvanizing process. The flow and temperature distribution in a base-case zinc pot was compared to that in other two optimized zinc pots, one of which had a dam between ingot and snout and another one had a reduced heating power. The simulation shows that the dam impedes the flow of low temperature liquid zinc around zinc ingot to strip and increases the fluctuation of zinc level. By reducing the heating power, however, the fluctuation of zinc level could be suppressed.

Heat Pump Drying

The distribution of local temperature, moisture and velocity gradients obtained in CFD calculations can be used to develop models for predicting the parameters in a drying process. This article reports a preliminary result on the efforts to characterizing the performance of a heat pump dryer using Computational Fluid Dynamics (CFD). A three dimensional, pressure based, transient, laminar, incompressible model of heat pump drying of banana slices using Ansys 14.5 (15), a CFD package- FLUENT was investigated. Turbulent cases were also examined. The geometry was considered as elemental volume with symmetrical walls while the banana slices were designed as solids with pores containing a mixture of water and air. Parameters/variable/geometry investigated include velocity, moisture and temperature distribution of the air within the dryer and of the banana slices. The result of the numerical simulation was validated with experimental results from a heat pump dryer and there were agreements. The model is successful in predicting the temperature profile and mass fraction of moisture. Keywords— Ansys, Banana, Computational Fluid Dynamics (CFD), Contour plots, Drying, Velocity and temperature distribution

Insulation Performance

The influence of the height of three-level hang wall on smoke insulation effect was study through simulation. One corridor connected to a room was constructed by computational fluid dynamics (CFD) software, then the smoke and the temperature distribution under different height of three-level hang wall were investigated. The result shows that the three-level hang wall played a good role on smoke insulation and the smoke and heat insulation performs the best when the height of three-level hang wall is 0.9m, 0.7m and 0.5m respectively. However, with the continuous development of the fire, the hang wall will eventually fail under all setting conditions.

Generation Mechanisms

Reducing tire noise has been a topic of increased focus in the recent years in industrial countries in order to decrease road traffic noise. Computational fluid dynamics (CFD) simulations conducted using ANSYS FLUENT are presented here to provide a better understanding of the small-scale noise generation mechanisms due to air-pumping at the tire-road interface. The CFD model employs a large eddy simulation (LES) turbulence modeling approach, where the filtered compressible Navier-Stokes equations are solved for simple groove geometries with a moving bottom wall that represents the deformation due to the tire movement along the road surface. A horizontally moving wall is used to represent the motion of the tire groove in and out of the contact patch while the deformation of the groove is prescribed. Temporal and spatially accurate pressure fluctuations are utilized to determine sound pressure levels and dominant frequencies. In addition to an understanding of noise generation mechanisms in such grooves, the CFD model developed here can potentially provide a series of control parameters that can help optimize the tire performance in terms of tire acoustics.

Many of the casualties occurring during these events can be attributed to the collapse of residential houses, and it is thus required to gain knowledge about the failure mechanism of these structures. Multiple variables can lead to various flow conditions that will in turn represent different load pressures over the house; among these, the type of the material (used in the construction), the orientation angle in respect to the main flow direction, the shape of the structure, and the urban density (blockage ratio), are relevant. In the present paper, small scale experiments are compared with CFD simulations performed with openFOAM in order to obtain a numerical model than can predict different combinations of load pressures for various flood events.</p><p> </p><p>The present study aims to represent different “typical Dutch” houses near or close to a dam break in which rapid high flow velocities and depths can be presented. The flow conditions and load pressures outputs are compared to physical results in order to validate the numerical model.</p>
