摘　　要：采用BOUT++输运程序与PFCFlux程序的耦合对CFETR包层第一壁上的能量沉积情况进行了模拟。研究发现,当湍性输运系数为50m^(2)·s^(-1)时,最外闭合磁面上的极向平均平行热通量为14058.5MW·m^(-2),进入刮削层的等离子体功率Psol的值为197.4MW;CFETR包层第一壁上的能量沉积主要集中于真空室壁靠近中心螺线管的高场侧区域,最大热通量出现在这一区域的中间部分。The power deposition on the first wall of the CFETR blanket is simulated with the PFCFlux program coupling the BOUT++transport program.It is shown that when the radial turbulent transport coefficient is 50m^(2)·s^(-1),the poloidal average parallel heat flux on the Last Closed Magnetic Surface is 14058.5MW·m^(-2),and the plasma power entering the scrape off layer is 197.4MW.The power deposition on the first wall of the CFETR blanket is mainly concentrated in the high field side region of the vacuum chamber wall close to the central solenoid,and the maximum heat flux occurs in the middle part of this region.
