The gain of the isoplanatic angle of the multiconjugte system is deduced compared to classical adaptive optics system. Based on the deduction, the maximum gain conjugate position of level and upright-propagation is analysised. For the first time, the upright-progagation analysis had been combined with Hefei China's domestic air refractive index structure constants, which are different in four seasons...
Based on Spalart-Allmaras turbulence model, numerical simulation on NACA0015 airfoil with Gurney flap is carried out in this paper. Then the double Disks multiple stream-tube model is introduced to predict aerodynamic performance of VAWT of NACA0015 airfoil with Gurney flap. Results show that the Gurney flap can improve the lift coefficient of the airfoil and the height of the flap plays an important...
Natural ventilation is one of the effective ways to improve the indoor air quality and save energy. The surface pressure distribution was studied by scale model wind tunnel experiment and CFD method, based on which the differential pressure of air inlet and outlet opening was obtained. The differential pressure was taken as boundary condition when studying internal natural ventilation and the influence...
This paper has investigated the theory and application of the environmental applicability of equipment based on GIS. The authors have established the mathematics model of the environmental applicability of atmospheric laser communication equipment system. In this article they have elaborated the evaluation method of the environmental applicability of laser communication equipment. Finally they presented...
