Abstract
Study of transient heat conduction in 2.5D domains using the boundary element method L. Godinho, A. Tadeu & N. Sim6es Department of Civil Engineering University of Coimbra, Portugal Abstract This paper presents the solution for transient heat conduction around a cylindrical irregular inclusion of infinite length, inserted in a homogeneous elastic medium and subjected to heat point sources placed at some point in the host medium. The solution is computed in the frequency domain for a wide range of frequencies and axial wavenumbers, and time series are then obtained by means of (fast) inverse Fourier transforms into space-time. The Boundary Element Method (BEM) is then used to evaluate the temperaturefield generated by a point source in the presence of a cylindrical inclusion, with a non-circular cross-section, inserted in an unbounded homogeneous medium. Simulation analyses using this model are then performed to study the transient heat conduction in the vicinity of these inclusions. 1 Introdu
