bibo:abstract
  • A recently developed spatial differencing scheme, Linear Characteristic (LC) scheme is compared with some traditionally used schemes such as Step Difference (SD), Diamond Difference (DD), and Step Characteristic (SC) scheme by analyzing the truncation error calculated numerically in slab geometry. Those four candidate schemes are applied to one simple source sink problem and two criticality problems (one is calculation of multiplication factor and the other is slab critical half thickness). The calculated results are then examined by some equitable measures of error. It is concluded that the LC scheme is terribly more powerful than any other candidate scheme that has been prevalent up to the present time. Moreover, the LC scheme estimates integral parameter such as multiplication factor and critical half thickness much more efficiently than SD or SC scheme. This is due to the fact that the fortuitous error cancellation, which occurs when the deviations of cell average flux are summed over the whole gamut of spatial meshes, happens much more favorably to the LC scheme.

  • 최근 개발된 유한차분법의 하나인 선형특성(LC)법을 절단오차의 분석을 통하여 계단형차분(SD)법, 다이아몬드형차분(DD)법, 그리고 계단형특성(SC)법과 비교했다. 제시된 4가지 방법들이 선속 계산문제, 유효증배계수 계산문제, 그리고 임계평판 두께 계산문제에 적용되었으며, 그때 계산된 결과들은 몇몇의 절단오차 측정 기준들에 의해 평가되어졌다. 본 연구의 주요 결론으로, 모든 경우에 있어서 어느정도 기대했던 바와 같이 선형특성법이 가장 우수하다는 것이 밝혀졌으며, 특히, 선형특성법은 유효증배계수와 임계평판두께 같은 적분 인자들을 정확하게 계산하는 데, 이는 선형특성법이 다른 방법들에 비해 오차소거(Error Cancellation) 작용이 효과적으로 일어나기 때문으로 밝혀졌다.
