Heat-transfer and flow-friction characteristics of woven-screen and crossed-rod matrices

Abstract : Woven-screen or crossed-rod types of matrices may be of interest as fuel-element geometries for certain types of nuclear reactors as well as in many other heat-transfer and mass-transfer systems. Basic heat-transfer and flow- friction design data for these geometries are presented graphically, in nondimensional form, for a range of Reynolds numbers from 5 to 100,000 and matrix porosities from 0.60 to 0.83. Algebraic equations which adequately represent these data are also given and these may be used for interpolation and, at least tentatively, for a limited extrapolation beyond the range of porosities covered in this program.
