P. Benz et al., RADIAL MASS DISPERSION COEFFICIENT OF CER AMIC FOAM STRUCTURES IN CONVECTIVE FLOW, Warme- und Stoffubertragung, 29(2), 1993, pp. 125-127
The radial mass dispersion coefficient of ceramic foam structures with
pore finesses of 10, 20, 30 and 50 PPI (pores per inch) in convective
flow is determined by means of the injection method (methane as trace
r gas). For empty tube velocities of ca. 0.6-6 m/s we obtain Pe(p) = u
0 . p/D(r) = 8 (+/- 30%) where p: average pore diameter.
