Quadir, Ghulam Abdul Asymptotic waveform evaluation (AWE) Conduction Fourier Non-Fourier Transient Interface circuits Fourier analysis Link to publisher's homepage at www.elsevier.com In this paper, asymptotic waveform evaluation (AWE) has been successfully used for fast transient characterization of Fourier and non-Fourier heat conduction. The Fourier and non-Fourier equations are reduced to a system of linear differential equations, respectively, using finite element method and then solved with AWE. Besides providing equivalent accuracy in its solution, it is also shown that AWE is at least three orders faster in term of computational time as compared to conventional iterative solvers. Its accuracy is also independent of the time step used and it has the capability of providing local transient solution. However, the moment matching process in AWE is inherently ill-conditioned and thus may yield unstable response even for stable system. This numerical instability is addressed and two stability schemes are also successfully implemented to yield stable and accurate solutions from AWE. The limitation of AWE is also discussed. 2009-08-06T12:50:09Z 2009-08-06T12:50:09Z 2007-10 Article International Journal of Heat and Mass Transfer, vol.50 (21-22), 2007, pages 4400-4408. 0017-9310 http://www.sciencedirect.com/science/journal/00179310 http://hdl.handle.net/123456789/6690 en Elsevier Ltd. |
