摘　　要：为研究啤酒发酵罐内发酵液的动量和热量分布,应用传递过程原理和计算流体动力学(CFD)方法,建立了啤酒发酵后期冷却阶段发酵液动量和热量传递的CFD模型,并进行数值模拟,结果表明:啤酒发酵后期冷却阶段发酵液温度分层严重;流体在发酵罐中产生了分层对流现象,这与一般认为的发酵罐内流体做整体环形对流运动不同。利用CFD方法可以较好地模拟发酵后期冷却阶段发酵液动量和热量的变化过程,所得结果可作为研究啤酒发酵温度控制的基础资料。A cooling process for fermenting liquor was modeled and simulated using the Computational Fluid Dynamics （CFD） method. The calculated results for temperature field of the fermentation liquor were compared with those from the measuring values during a practical production process. The simulation results revealed the hydrodynamic and energy conditions inside a fermentation jar, which provided a solid fundamental for temperature control of a fermenting liquor during beer brewery.
