The thermophysical properties of bone cement are important parameters for its application in the orthopedic treatment. This article focused on the thermal evaluation of the low-melting-point metal(Bi In Sn alloy), which has been proved to be an excellent bone cement. Firstly, the basic thermophysical properties of Bi In Sn alloys with different melting points were ***, 15 fresh porcine femurs placed in the saline bath, bone cements with different melting points and amounts were injected into the bone cavities, respectively. Thermocouples were used to measure the temperature changes of the bone-cement interface and peripheral bone tissue. The possibility of thermal necrosis was evaluated. Moreover, a three-dimensional human knee model was built to numerically assess the effects of thermal parameters, such as melting point and latent heat on tissue temperature distribution. All the experimental and numerical results implied the heat distribution in the tissue depended on the thermal performances of liquid metal bone cement(LMBC). For LMBC of the same melting point, with increased amounts, the damage to the bone tissue is more severe, while for the same amount of different melting point LMBCs, with the higher melting point, which will lead to more serious damage to the tissue. Also, higher latent heat of LMBC has distinct longer solidification process, which may cause irreversible damage to surrounding tissues. Therefore, in the future, for different clinical surgery needs, the appropriate liquid metal bone cement can be obtained by adjusting the thermal parameters.

基于量纲分析方法,实验研究不同烧结矿颗粒直径填充床内的流动阻力特性。研究结果表明:当颗粒直径一定时,床层内单位料层高压降随颗粒表观流速的增大呈非线性关系增大。当颗粒表观流速一定时,直径较小的颗粒床层内由于颗粒比表面积较大导致流动阻力损失也较大。颗粒雷诺数Re_p较低时,床层内颗粒摩擦因子f_p随Re_p的增加而迅速减小;Re_p较高时,随Re_p的增加,f_p下降趋势较为平缓,并最终不发生变化。由于计算误差较大,现有的预测关联式不适用于求解烧结矿颗粒床层内的流动阻力损失。通过实验数据拟合得出了能够描述烧结矿颗粒床层内流动阻力特性的实验关联式,平均计算相对误差为7.93%,显示了良好的预测性能。

以某钢铁企业年产390万t烧结矿为研究对象,基于多孔介质理论和局部非热力学平衡双能量方程模型,建立烧结矿竖罐内气固稳态传热模型,并借助Fluent软件及其二次开发平台,以回收的空气热量和空气为判定基准,对不同操作参数对竖罐内气固传热过程的影响进行模拟研究。研究结果表明:回收的空气热量和空气随烧结矿入口温度的升高而逐渐增加,随烧结矿颗粒直径的增大而逐渐减少;随着气料比的增加,回收空气热量的增加趋势逐渐变缓,空气则呈现出先增大后减少的趋势;随着空气入口温度的升高,回收的空气热量逐渐减少,空气则逐渐增加。在实际操作工况改变时,通过气料比的调节可达到最佳气固换热效果,获得最大的空气。
