浮升力 meaning in Chinese
buoyancy lift
Examples
- On variations in airship uplift with height
飞艇浮升力随高度变化规律的研究 - It uses solar radiation to provide upward momentum to a mass of air , thereby converting the thermal energy into kinetic energy
它利用太阳辐射作为动力，为空气流动提供浮升力，将热能转化为动能。 - 2 ) . it has a great temperature gradient along the height in hot and cold plenums of cefr in steady state . the buoyancy force cannot be ignored because the flow velocity is low in the whole flow regions
冷热钠池在稳态工况下沿高度方向有很大的温度梯度，整个流动区域内的流速较低，浮升力的影响不可忽略； 3 - The complicated behavior and multiple states of indoor air convection are mainly related to the multiple physical processes , such as the thermal buoyancy , the solutal buoyancy and the mechanical ventilation
室内空气对流行为的复杂性与状态的多样性通常是多种物理过程相互作用的结果，如离散热源的热浮升力、离散污染源的浓度浮升力及机械通风等。 - In the last part , an experiential formula for nondimensional thermal stratification height is obtained , which includes inlet temperature t , inlet velocity v , heat transfer of the wall body q and the distance of heat source l . in order to obtain a more realistic result , the ? model is used to simulate the airflow and the buoyancy item is treated by boussinesq hypothesis . the paper investigates the flow field of the displacement ventilation in an office by a numerical method
两方程湍流模型为基础的壁面函数处理方法,对热浮升力项采用了boussinesq假设,得到了收敛的温度场、速度场分布。在此基础上,给出了热力分层高度的计算方法,并分析了送风温度、送风速度、围护结构传热和热源分布等因素对热力分层高度的影响。
