It differs from the preceding cases in that a transient is considered. Another difference is that a cylindrical-polar coordinate grid is employed. A schematic diagram of the geometry follows; note, however, that the ratio of the wall thickness to the inner diameter in the diagram is not to scale. ^ .-----.--------------------------. | /***.-.***\ \ |r /**/ \**\ \ | |**| |**| | |**| |**| | \**\ /**/- - - - - - - - - - - - -/ \***`|'***/ temp. fixed to zero / `--|--'--------------------------' | z----> Fixed heat flux at inner surface ENDDIS ************************************************************ Group 1.
