| Abstract: | A sell-adaptive precise algorithm in the time domain is presented for convective heat transfer problems. By expanding variables at a diseretized time interval, a time and space coupled problem is converted into a series of boundary value problems. Based on a finite element method, a recursive and sell-adaptive computation is conducted without the requirement of additional assumption and iteration for non-linear analysis. A couple of examples with high accuracy are shown. |
