ANALYTICAL AND NUMERICAL STUDY OF HEAT TRANSFER IN FINS

  • In this paper, one-dimensional heat transfer
    problems that can be approached by different methods was
    presented. The analytical approach using the direct solutions
    of differential equations was used to verify the approximate
    solution. In this paper the analysis was focused on the
    insulated fin tip. A more practical approach is the use of a
    suitable numerical method. The finite volume method seems to
    provide a good approach in using these complex problems
    with a variety of boundary conditions and the usage of
    MATLAB programming. An iterative technique may frequently
    yield a more efficient solution to the nodal equations than a
    direct matrix inversion. With the help of finite volume method
    and MATLAB programming for insulated and uniform crosssectional area of the fin problems and with applying GAUSSSEIDEL iteration method which is used to solve and calculate
    the nodal temperature distribution at different positions along
    the fin rod, it was found that the approximate solution is very
    close to the analytical solution. IRJET-V8I1251.pdf (1٫0% u)
