模拟实验

An experiment on forming of cross-hatch on the ablation material surface has been done under the condition of Mach 5 and tur-bulent boundary layer regime.Artifitial disturbances created by randomly setting several pins along a line perpendiculer to the flow direction have shown stochastical character of local cross-hatch and independence of global orderly structure,therefore the pattern appeared fractal behavior.

And has brilliant prospect due to its simple structure, good economy and energy saving performance.Based on the full scale passive solar experimental building in DUT, in which the researcher carried experiment as the main method and the CFD simulation as the minor method, the research focuses on passive ventilation formed by the Trombe wall. This paper analyzed the indoor thermo and humidity performance of passive solar building with Trombe wall, and the different ventilation patterns in different seasons, revealing the role of passive ventilation in improving indoor environment. Also the paper researched the characteristics of passive ventilation on air flow and heat transfer mechanicsms, and put forward the best control and adjusting method. Meanwhile the paper gained an empiric formula in use of calculating the natural convection heat transfer and found the key factor of influing the indoor environment.
