收敛判断flux report中radiation heat transfer rate怎么一回事？
|
|
问题：达到要求残差后，检查flux report发现其他几项net result都还行就是radiation这一项很大。这是怎么回事？这说明没有收敛吗？ radiation heat transfer rate总量大概在2000w左右，但是net result达到了快400w。 Radiation Heat Transfer Rate (w) -------------------------------- -------------------- furnace_1 1857.7213 furnace_2.1 -415.75629 furnace_2.2 73.207432 furnace_2.3 -99.090895 furnace_3 -346.88424 furnace_4 31.087633 pressure_outlet -12.189919 pri_&_sec_neck -1.3133333 primary_in -0.023508304 primary_in_wall -11.4986 probe -178.46584 secondary_in -16.449077 secondary_in_wall -116.27757 shoulder_wall -176.12711 side_wall -189.43921 ---------------- -------------------- Net 398.50073 其他几项flux report 和net reslut如下： 1，mass flow rate Mass Flow Rate (kg/s) -------------------------------- -------------------- default-interior -0.064587268 furnace_1 0 furnace_2.1 0 furnace_2.2 0 furnace_2.3 0 furnace_3 0 furnace_4 0 pressure_outlet -0.00053977473 pri_&_sec_neck 0 primary_in 3.5314289e-05 primary_in_wall 0 probe 0 secondary_in 0.00049236408 secondary_in_wall 0 shoulder_wall 0 side_wall 0 DPM Mass Source 1.2095751e-05 ---------------- -------------------- Net -6.1345613e-10 2，total heat transfer rate Total Heat Transfer Rate (w) -------------------------------- -------------------- furnace_1 1985.6762 furnace_2.1 -450.52071 furnace_2.2 55.445269 furnace_2.3 -112.79937 furnace_3 -383.58327 furnace_4 12.244041 pressure_outlet -292.4911 pri_&_sec_neck -1.2658433 primary_in 0.044210239 primary_in_wall -12.358163 probe -189.60414 secondary_in 124.32721 secondary_in_wall -116.26121 shoulder_wall -174.56474 side_wall -192.17994 DPM Enthalpy Source -258.62446 ---------------- -------------------- Net -6.5160331 3,total sensible heat transfer rate Total Sensible Heat Transfer Rate (w) -------------------------------- -------------------- furnace_1 1985.6762 furnace_2.1 -450.52071 furnace_2.2 55.445269 furnace_2.3 -112.79937 furnace_3 -383.58327 furnace_4 12.244041 pressure_outlet -751.1444 pri_&_sec_neck -1.2658433 primary_in 0.044210019 primary_in_wall -12.358163 probe -189.60414 secondary_in 124.32721 secondary_in_wall -116.26121 shoulder_wall -174.56474 side_wall -192.17994 Heat of Reaction Source 168.50009 DPM Sensible Enthalpy Source 38.733676 ---------------- -------------------- Net 0.68889531 求高手解释一下。 |
