A three-dimensional analysis model based on the finite element method (FEM) is developed,which can derive the evolution and distribution characteristics of heat flux deposited on the divertor plate from the surface temperature measured by infrared thermography diagnostics.The numerical simulations of surface heating due to localized power bursts and the power deposition calculations demonstrate that this analysis can provide accurate results and useful information about localized hot spots compared with the normal one-and two-dimensional calculations.In this paper,the details of this three-dimensional analysis are presented,and some results in ohmic heating and electron cyclotron resonant heating (ECRH) discharge on HL-2A are given.
