Hybrid numerical method applied to multilayered hollow cylinder with vapor flow

Abstract: This paper deals three-dimensional axisymmetric quasi-static coupled thermoelastic problems for time-dependent boundary condition. The water vapor temperature and pressure relation assumed for the inner boundary. The water vapor temperature and pressure data were obtained from a thermodynamic steam table. Laplace transform and finite difference methods are used to analyze problems. The solution is obtained by using the matrix similarity transformation and inverse Laplace transform. We obtain solutions for the temperature and thermal deformation distributions in a transient and steady state. Moreover, the computational procedures established in this thesis, can solve the generalized thermoelasticity problem for multilayered hollow cylinder with nonhomogeneous materials.
