Heat Transfer Characteristics and Pressure Drop of U-type Channel in Vacuum Distillation Process for Titanium Sponge

Blockage of the U-type channel exacerbates intermittency production, and clarifying heat transfer characteristics pressure drop is an effective way to address this problem. The flow fluid in are experimentally investigated study. According experiments, coefficient between 59.95 200.29 W/m 2 ⋅K increases with velocity temperature. Because usually accompanied by a change energy loss fluid, evaluated experimentally. results demonstrate that friction straight tube section accounts for 80% loss. A bent 90° recommended instead right-angle reduce drop. dimensionless relation regarding Nusselt number presented predict characteristics. We provided proposals problem blockage channel, helpful production consumption improve quality titanium sponge.
