Application of computational fluid dynamics (CFD) used in simulation of flow distribution for air condition ZHANG Zheng , WANG Jin-feng , XIE Jing , TANG Yi aemail: 522017934@qq.com, bemail: jfwang@shou.edu.cn, cemail: jxie@shou.edu.cn (College of Food Science and Technology, Shanghai Engineering Research Center of Aquatic-Product Processing & Preservation, Shanghai Ocean University, Shanghai 201306, China) Keywords:Air condition; Energy-saving; Comfort; CFD; Numerical Simulation Abstract.
However, due to many factors to be considered in the process of simulation (such as the impacts of building materials , coupling modes of pressure and airflow and grid accuracy, etc.), coupled with complicated settings in calculation , therefore there are still not a large number of documented research about the running optimization of indoor air conditioning.

This defect can be realized by introducing a different material into the structure or by altering the physical and geometrical properties of a layer in the structure, allowing the appearance of new electromagnetic modes within the band gaps as evanescent modes.
In this representation, A denotes the dielectric material (Pbs), and B represents the superconductor.

On the contrary, FEM is applicable to almost all kinds of nonlinear materials.
It is applicable to cracks in isotropic and anisotropic linear materials.
Numerical examples and discussions Edge crack between two isotropic materials The rectangular plate with an edge crack shown in Fig. 4a is comprised of two materials with the elastic properties =100GPa, =10GPa, ==0.3, in which subscripts 1, 2 refer to material 1 and 2.
Both materials hold .

The fire resistance of reinforced-concrete structures can be improved by their surface modification with protective materials of different chemical nature.
The adhesion strength index increases for both materials to a heating temperature of 573 K, and then decreases as a result of thermo-oxidative degradation of polymethylphenylsiloxane and increased porosity.
Therefore, the fire protection of coated materials will depend on the state of the surface, which changes with heating due to the formation of pores and cracks in the physical and chemical processes that take place in the coatings.

Introduction Cellulose-based superabsorbent materials, as one of three categories of natural superabsorbent materials (starch, cellulose and synthetic polymers), are developing rapidly.
So how to prepare inexpensive but high quality of superabsorbent materials with abundant celluloses, is a very important research topic, which has been the big part of the superabsorbent materials[3].
Although there are lots of new technologies and new materials, traditional cotton gauze still is the main materials of wound care.

Materials and Methods The choice of LEDs based on GaP with an effective wavelength of 590 nm as the object of research in this work is due, in particular, to the fact that they are characterized by all the main types of radiative recombination observed for LEDs based on various semiconductor materials.

As we got closer to the brazed zone, the base materials grains became larger and the grain limits became more evident (thickened), as ca be observed in figure 5.
The brazed joint region revealed a good quality joint between the materials, with good wetting from the part of the brazing alloy (fig. 6).
Microscopic aspect of brazed joint zone (OM 100) The brazed joint region does not reveal oxides between the brazing alloy and base materials (sign of exposure of air or moisture) or lack of penetration of the brazing alloy.
Ongoing Research The use of brazing for joining stainless steels used at high temperatures will continue and be expanded to other brazing processes and other materials.
Also, the mechanisms that governs the phenomena that take place during brazing of these materials will be studied deeper by analyzing the brazed joints using other investigating techniques like: SEM (Scanning Electronic Microscope), X-Ray Diffraction, etc. to determine the transformations that took place in base materials and brazing materials during brazing process.

The proportion of tensile damage and compressive damage will change while the number ‘a’ changes, so it can be used to study the mechanical damage behavior of different materials.
