碩士 === 國立成功大學 === 航空太空工程學系 === 84 === The Zonal method, which is usually known as Hottel's zonal
method, is one of the most widely used methods for
calculating radiation heat transfer in practical
engineering systems. The purpose of this dissertation
is to study the effect of the multigrid method on convergence
rate for heat transfer problems with radiation. For all
problems in this research, we observe the performances
between single grid and multigrid, and compare with the rat
io of CPU times and work units.
Firstly, we test the pr oblem of conduction with radiation in
order to understand the performances of the multigrid method.
The results indicate that the performance of convergenceis
converged oscillatly when NR = 0, but it is converged
smoothly when NR > 0.
Finally, we applied the multigrid metho d to the steady state
heat transfer problem of nature convection with radiation in
a two-dimensional rectangular enclosure. It is found that
the zonal me thod combined with multigrid method also has
good speed-up performance in our calculations.
