Heat transfer and axial dispersion in packed beds

Influence of Gas-Solid Heat Transfer on Rapid PSA

“…However, its validity has been questioned by various authors (Gunn and De Souza, 1974;Dhingra et al, 1984). Nevertheless, Table 1 shows that a range 1 to 6 for the particle Nusselt number is very plausible for describing gas-solid heat transfer in packed bed adsorbers.…”

An analysis of convective dispersion and reaction in the fixed-bed reactor

“…Because the pattern of diffusive interaction between particles and fluid is the same in reactive and active beds it is expected that the dispersion coefficients would be the same because of similarity in the constituent diffusive and dispersive processes. Experiments with active particles including validation studies have been carried out by Gunn and England [14], Gunn and de Souza [17], Bashi and Gunn [4], Gunn and Misbah [15] and Gunn and Misbah [16].…”

3-Dimensional Flow Modeling of a Proposed Hanford Waste Treatment Plant Ion-Exchange Column Design

“…The paper by Kunii and Smith (1961) provided the best data set for our purposes (i.e., see their Figure 10 for a comparison). Listed in the reference section of this report are several other published papers with regard to this subject (i.e., Gunn and De Souza [1974], Rowe and Claxton [1965], Pfeffer and Happel [1964], Kunii and Suzuki [1967], and Kunii and Smith [1960]). …”
