Simulation of heat transfer of supercritical water in obstacle-bearing vertical tube 1 first-author 1 corresp Corresponding author. E-mail address: jqshan@mail.xjtu.edu.cn Corresponding author.

In this paper, the heat transfer downstream an obstacle-bearing vertical tube is simulated by the CFD code of Fluent 6.1, using an adaptive grid in the supercritical condition. The reliable results are obtained by the RNG k - ε model using the enhanced wall treatment. The blockage ratio and local temperature of obstacle affect greatly the heat transfer enhancement, and the resultant influence region and decay trend are compared with the existing equations.
