Numerical Model of Heat Transfer in a Rod Bundle With Helical Wire Wrap Spacers

Porous body model for predicting temperature distributions in wire wrapped fuel and blanket assemblies of a LMFBR

“…[1][2][3][4][5][6][7][8][9] have been classified in Table I The present thesis describes the development of a relatively simple model which is similar in principle to the one which has long been successfully used for heat and mass transfer in fixed beds of packed solids (Refs. [10][11][12][13].…”

“…Since we are solving a set of differential equations the mesh size n* can be of any convenient size. Unlike in subchannel analysis methods, the spacing between (2)(3)(4)(5)(6)(7)(8)(9) nodes does not have to be taken equal to the distance between the centroids of the subchannels but it may be so taken. In region II it is possible to use more than one mode in a direction perpendicular to the wall.…”
