The conjugate gradient method is an efficient means of solving
large sparse symmetric positive definite systems of linear equations
which arise from finite difference approximations to self-adjoint
elliptic partial differential equations. In obtaining a solution,
the conjugate gradient method successively minimizes a certain norm
of the error in different orthogonal...
In the event of a small break loss of coolant accident
(SBLOCA) in a nuclear reactor, cold fluid is injected through
the reactor system high pressure injector to compensate for
the coolant loss. When this flow rate is less than a critical
value, however, the hot fluid in the cold...
