| 제목 | Numerical modeling of 3D monolithic catalyst channel and inverse estimation of transient internal gas flow distribution |
| 초록 | This study proposes a detailed three-dimensional model of a monolithic catalyst channel. The balance equations were linearized in the axial direction and discretized in the radial direction using a triangular and quadrangular prism mesh. This linearization process converts a series of partial differential equations to ordinary differential equations, which enables the simulation of the transient behavior of heat and mass transfer within the monolith channel. Due to the model’s first-principle nature, it can accommodate unspecified and time-varying operational conditions without assuming homogeneous conditions or typical parabolic distributions. By defining the error of the measured gas temperature at the channel outlet as a loss function and solving its minimization problem, an additional inverse framework was established to determine the inlet flow profile. By applying the profile to the model once more, the temperature and mass flux distributions within the structure can be calculated in time series form. Additionally, it can aid in the simulation of catalytic reactions by accurately estimating the mass flux, which is more difficult to precisely measure than temperature. |
