Mini-TBM will be tested in chinese LiPb experimenttal loop Dragon-IV to validate the thermal-hydraulic effect of DFLL-TBM, such as dual-flow fields heat transfer, temperature fields, velocity fields, flux distribution of liquid lithium lead and helium gas. It is difficult to measure the detailed dual-flow fields of liquid metal LiPb and helium gas in mini-TBM. Three dimensions numerical analysis of the LiPb and helium gas flow and heat transfer in Mini-Test Blanket Module (TBM) therefore has been carried out using the CFD code FLUENT. The detailed dual-flow fields, which include temperature, velocity, pressure and heat transfer of liquid LiPb and helium gas, are presented to support for the test of mini-TBM, and to supply more robust database and make a significant joint contribution to the future TBM testing in EAST and ITER, and also optimize and improve the design of DFLL-TBM system for ITER.

Abstract A fundamental understanding of how reactor parameters influence the fiber surface temperature is essential to manufacturing high quality optical fiber coatings by chemical vapor deposition (CVD). In an attempt to better understand this process, a finite volume model has been developed to study the gas flow and heat transfer of an optical fiber as it travels through a CVD reactor. This study showed that draw speed significantly affects fiber temperature inside the reactor, with temperature changes up to 45% observed under the conditions studied. Multiple heat transfer modes contribute to this phenomena, with convection heat transfer dominating the process.
