CFD modelling of inorganic membrane modules for gas mixture separation

CFD (computational fluid dynamics) analysis of a novel reactor design using ion transport membranes for oxy-fuel combustion

“…In the work of Hong et al [16e18], it was shown that the local value at the membrane surface must be used in order to separate the contributions of the mass transfer resistances and those associated with the permeation process. This modification was validated experimentally in Hunt et al [20].The flux equation represented by equation (8) has been validated in our earlier work and the details of D v , K r , K f constants can be found in Ref. [36].…”

“…Coroneo et al [8] performed CFD modeling of inorganic membranes for gas separation. The analysis showed that the transport mechanism has great impact on the permeation rate.…”

Computational fluid dynamics study of hydrogen generation by low temperature methane reforming in a membrane reactor

“…The steady-state 2D CFD model employed in our study is based on the previously reported CFD models [26,27,34]. We assume a pseudo-homogeneous description of the catalytic bed [22,29], therefore the computational domain representing the catalytic packed bed is solved as a continuum.…”

“…Goto et al [28] studied H 2 permeation rate through a composite membrane with a Pd film coated on a porous ceramic tube and defined a numerical model based on the combined resistances of the Pd film and the composite support. Coroneo et al [26,27] investigated mass transfer characteristics of PdeAg membrane H 2 separation modules experimentally and numerically using Computational Fluid Dynamics (CFD). Though porous ceramic membranes provide higher permeabilities, dense Pd membranes perform much better in SMR due to their exceptional selectivity.…”

Simulation of binary gas separation through multi-tube molecular sieving membranes at high temperatures

“…(1) and (2) represent the mass transfer between feed side and permeate side and are derived from the following formulas [27,28] where Q and Q H2 are the total permeate flow rate and the hydrogen permeate flow rate in one computational cell, respectively; J H2 is the hydrogen permeate flux; A is the permeable area in a cell; and V is the computational cell volume. The source terms are zero if the computational cell is not in the permeable region (such as cells 1, 2 and 3 in Fig.…”
