Computational Fluid Dynamics This discipline has been quite mature , is an important sign of its maturity in recent decades a variety of commercial CFD software package , emerging and growing number of engineering problems , and gradually became effective treatment works means. In this paper, computational fluid dynamics numerical simulation method , the application of CFD software several typical engineering issues , and get meaningful results . ZK240 type central air conditioning chassis Shenling CFD analysis of the flow characteristics to the chassis the overall pressure drop minimum objective function has been adjusted for the relative position of each functional segment , the optimized chassis model , the overall pressure drop than the original model of the chassis reduced by 14 % ; simulation to optimize the the chassis model under working conditions, the speed vector , pressure and temperature contours , requires the use of the power characteristics of the wind turbine components are given in the recommendations and guidance , to provide a reference for the technical staff . Four divisions jumper in LGJ400/50 wire shape coefficient and wind the partial numerical calculation and analysis , simulated LGJ400/50 wire shape coefficient , and the standard of comparison , verify the appropriateness of the standard ; analog four split jumper partial wind , get wind partial displacement and proportional to the square of the wind speed , the same wind speed , ice coating the wire monsoon displacement larger than the wires or no ice . Flow field analysis and design in the cell culture fluid shear stress experimental device to determine the location of the the cuboid cell culture medium suitable flow chamber geometry and cell growth area ; shear stress calculation results show that the cell culture medium as Newton fluid approximation ; Finally, the cell culture medium as a non-Newtonian fluid , obtained by fitting the flow and shear stress relationship .
