U型通道的堵塞加剧了生产的间歇性，明确通道的传热特性和压降是解决这一问题的有效途径。本研究对通道内流体的通道传热和流动特性进行了实验研究。根据实验，传热系数在59.95和200.29W/m2·K之间，并且随着流速和流体温度的增加而增加。由于压降通常伴随着流体能量损失的变化，因此通过实验评估能量损失。结果表明，直管段的摩擦损失占能量损失的80%。建议使用 90° 弯管代替直角管，以减少压降。提出了关于努塞尔数的无量纲关系来预测传热特性。我们提出了解决U型通道堵塞问题的建议，这有助于降低生产能耗，提高海绵钛的质量。
Blockage of the U-type channel exacerbates the intermittency of production, and clarifying the channel heat transfer characteristics and pressure drop is an effective way to address this problem. The channel heat transfer and flow characteristics of the fluid in the channel are experimentally investigated in this study. According to the experiments, the heat transfer coefficient is between 59.95 and 200.29W/m2⋅K and increases with the flow velocity and fluid temperature. Because the pressure drop is usually accompanied by a change in the energy loss of the fluid, the energy loss is evaluated experimentally. The results demonstrate that the friction loss in the straight tube section accounts for 80% of the energy loss. A bent tube of 90° is recommended instead of a right-angle tube to reduce the pressure drop. A dimensionless relation regarding the Nusselt number is presented to predict the heat transfer characteristics. We provided proposals to address the problem of blockage of the U-type channel, this is helpful to reduce production energy consumption and improve the quality of titanium sponge.
