Numerical methods in nuclear thermal hydraulics

Abstract

Numerical methods utilized for the solution of governing fluid flow equations are considered, with emphasis on the influence of the adopted schemes in the solution and the computational costs of the approximations. Consequently, the subject as presented is a mix between algorithmic, modeling, and algebraic aspects, keeping the usual separation in the type of partial differential equations. A detailed review of the theory manuals of the major thermal hydraulic codes permits the verification of the coherence of this approach. The verification of the validity of the solutions and the automatic sensitivity analysis of codes are also analyzed.
