Abstract: Numerical simulation
for Heat Transfer
at Chimney with variation material doneto know the
conduction phenomenon that happened in
chimney with convection boundary condition. Simulation done by solving governing
equations of conduction with convection boundary condition using finite element
approximation and finite
different approximation. Finite element approximation
done with makes
by mesh of
element, nodal coordinate and
determine convection boundary
condition with Galerkin formulation approximation. Finite
different approximation done
by solving governing equations with
ADI method for calculation conduction equation of x and y direction. Finite
element method and finite different
method solved with Fortran Power Station 4.0 and Matlab 7. Result of simulation
from both method shown as
visualization happen same
temperature distribution at chimney.
From both method
for same material
at YX=1 happen
difference equal to 1,6385
% and for
difference material at
YX=1 happen difference equal to 1,9033 %. From difference
both method shown that this method can be accepted for case of heat transfer at
chimney.
Key word: conduction,
