Consistent accelerated schemes for nonlinear coupling problems in reactor analysis Conference Paper uri icon

abstract

  • Conventional coupling paradigms used nowadays to couple various physics components can be inconsistent in their treatment of the nonlinear terms. This leads to usage of smaller time steps to maintain stability and accuracy requirements, thereby increasing the CPU time. This paper aims at finding accelerated schemes that will provide accurate solution fields for coupled reactor analysis problems that are non-intrusive in-order to use existing mono-physics codes in achieving consistent coupling. These schemes were applied to both 0-D and 1-D transient problems and results obtained verify the advantages of using the predictive and accelerated schemes.
