摘要:
人工心脏已进入临床发展阶段，溶血现象是制约人工心脏长久使用的一大难题。不正常的温度条件会使红细胞的正常生理机能和形态发生改变，从而影响其携氧能力。为研究人工心脏正常运转时的温升情况，先利用Solidworks软件建立轴流式血泵的三维仿真模型，然后基于ANSYS Workbench软件对血泵整体进行热流耦合温度场仿真，探究了定子绕组相阻值、血泵转速、定子外壳和泵外壳之间的气隙导热系数以及血液导热系数对血泵及血液整体温升的影响。结果表明，在满足血泵供血要求的前提下，适当减小定子绕组相阻值、降低转速可有效降低血泵整体温升，而气隙物质和血液导热系数的变化对血泵整体温度的影响不是很明显。
Abstract:
Abstract: Artificial heart has entered the stage of clinical development, and hemolysis is a major problem restricting the long-term application of artificial heart. Abnormal temperature conditions will change the normal physiological function and morphology of red blood cells, thus affecting blood oxygen-carrying capacity. To study the temperature rise of artificial heart during normal operation, a three-dimensional simulation model of axial flow blood pump is established by Solidworks software. Then the simulation of thermal-flow coupling temperature field of the blood pump is carried out based on ANSYS Workbench software to explore the effects of different levels of stator winding phase resistance, rotate speed, air gap thermal conductivity between the stator shell and pump casing, and the thermal conductivity of blood on the global temperature rise of the blood pump and blood. The results indicate that under the premise of supplying adequate blood, the appropriate reductions of stator winding phase resistance and rotate speed can effectively reduce the global temperature rise of the blood pump, while the changes of the thermal conductivities of air gap materials and blood only have trivial effects on the global?emperature of the blood pump.
