Validity and scalability of an asymptotically reduced single-channel model for full-size catalytic monolith converters
作者：
Highlights：
• We establish the condition for validity of a reduced model for multiple channels.
• The reduced model is verified with the full model for a 2-channel assembly.
• The reduced model preserves geometrical resolution and captures essential physics.
• In particular, it captures the conjugate heat transfer across the channels.
• Allows for modeling of real-size monolith converter comprising up to O(104) channels.
