摘　　要：为了探究流动型量热器的结构参数和加热功率对量热器内流体的温升的影响,采用Fluent软件建立流动型量热器模型对量热器内的流体进行模拟分析。设定内管径的尺寸Φ3 mm,模拟得出:管路外径的最佳范围为Φ4~7 mm;设置内管直径为3 mm,外管直径为6 mm,内管长度75 mm,外管长度为130 mm,温度为293.15 K,压力为0.1 MPa,流量为5 ml/min,模拟得出:纯水、乙醇、甲苯的最佳功率范围:0.124~0.371 W,0.170~0.507 W,0.354~1.064 W。In order to explore the influence of temperature rise of the fluid inside the calorimeter underdifferent structure parameters and different heating powers. The flow type calorimeter model was estab-lished by Fluent software to analyze the fluid inside the flow calorimeter. When the size of the inner diam-eter was 3 mm, the best range of pipe diameter was φ4 - 7 mm ; When the inner tube diameter is 3 mm,the outer tube diameter is 6 mm, the inner tube length is 75 mm, the outer tube length is 130 mm, thetemperature is 293.15 K, the pressure is 0.1 MPa, the flow rate was 5 ml/min, the optimum powerrange of the pure water, ethanol, toluene： 0. 124 - 0.371 W, 0. 170- 0.507 W, 0.354 - 1. 064 Wrespectively.
