What is it about?
Catalytic converters are widely used in automotive and many other applications. Their performance depends on the operating temperature that varies during the operation. This study presents a mathematical model based on the finite volume method for simulating transient heat transfer in a honeycomb catalyst substrate.

Why is it important?
The developed model showed reasonable prediction quality in simulation of transient heat transfer in the honeycomb catalyst. At the same time it utilizes at least 2 times less control volumes that leads to a reduction of necessary computational efforts.
Perspectives
Further works will focus on the implementation of the developed model into mathematical model simulated chemical processes in the catalyst block. It will allow to carefully predict the catalyst efficiency during transient engine operation and warm-up period.
