摘要: Abstract In the present study a three-dimensional (3-D) transient inverse heat conduction problem is solved using conjugate gradient method (CGM) and general purpose commercial code CFX4.2-based algorithm to estimate unknown boundary flux in any 3-D irregular domain. The advantage of calling CFX4.2 as subroutine calculation lies that many difficult but practical problems can be under this construction. Results obtained by solve these are justified based on numerical experiments. It concluded accurate fluxes estimated CGM except for final time. reason improvement singularity addressed. Finally, effects measurement errors solutions discussed.
