摘　　要：用粒子成像测速技术(PIV)和稳态法分别测量均相流体在热管生物反应器中湍流时的流场、温度场;从流体微元出发,用计算流体力学(CFD)的方法建立热管生物反应器的传热数学模型。实验与流体力学计算软件结果均表明,该反应器传热数学模型能够很好地模拟并预测反应器内流体的流场、温度场等,为热管生物反应器的数学模型及放大提供基本传热数学模型。The flow field and temperature field of the uniformity phase fluid were measured by PIV and the steadystate method during the state of onflow. Using the fluid differential unit, the heat transfer mathematic model of heat pipe bioreactor (HPBR) was established by the calculated fluid hydrodynamics (CFD). The experiment result and the calculating software for hydrodynamics proves that the mathematic model can well simulate and forecast the flow field and temperature field in HPBR, which will also provide the mathematic model and the magnify of HPBR with the basic heat transfer mathematic model.
