Parameters influencing aerodynamic flows and transition and influence of boundary layers on outer potential flow are presented , along with associated stall and drag mechanisms 而边界层理论受限于各种流体种类的假设,像是可压缩性、紊流、维度和热传。
Whenever assigning property data in a heat transfer problem , bear in mind that many properties ( especially liquid viscosity ) are very sensitive to temperature changes 在热传问题中需要指定物理性质时,请注意有许多物质?尤其是液体?的物理性质对温度变化非常敏感。
As for the dehumidifying conditions , the condensing rate for the humid air increases with reynolds number but decreases as the inlet temperature of cold water increases 同时湿盘管的热传量及除湿率亦也随著冰水入口温度的降低而增加,显热比随著冰水温度的降低而减小。
The experiments involve different branches of mechanical engineering knowledge , so we try to assign the students for maximum exposure to heat transfer , dynamics , thermo , fluid mechanics , etc 各项实验需应用机械工程领域中不同的知识,因此我们在分组时会尽可能使同学接触到热传学、动力学、热力学、及流体力学等领域。
6 . through numerical simulations , effects of the adsorbent bed configuration , thermal conductivity and permeability of the adsorbent are analyzed . some technologies of heat transfer intensification are revalued 通过吸附床内传热传质的数值模拟,分析了吸附床结构、吸附剂的传热系数和透过度对系统性能的影响,一些有关吸附床的强化传热技术被重新评价。
The preliminary experimental research is conducted to the process of heat and moisture transfer in building elements , hence an experimental technique is developed for the indirectly measurement of mass diffusivity and thermo - mass diffusivity of the moist porous media 对多层多孔结构内传热传湿过程进行了实验方法的研究和探讨,发展了间接测定多孔材料的质扩散系数和热质扩散系数的实验方法。
