Abstract: Using the FLUENT software, this paper taking the current code for the design of building structures as the comparison standard, have numerical wind tunnel simulation of the wind the surface wind pressure on low layer double slope roof. It focuses on the analysis of the effects of turbulence model selection on the numerical simulation results, such as Spalart-Allmaras、Standard k −ε、RNG k −ε、Realizable k −ε、Standard k −ω、SST k −ω and RSM, to provide a basis for the reasonable selection of turbulence models.

Abstract: At first, the paper introduces the international development trends of textiles, and indicates that we must conform to the ecological textile to resolve the green barriers. Then the paper introduces the concept and the essence of this ecological design, and raises the ways that achieves ecological textile from ecological evolving, ecological running, ecological designing, etc. At last, the paper introduces the ways of realizing ecological textile from four factors which are using regeneration material, reducing material consumption, elevating textile life and reusing the castoff textile.
