- •
A numerical model to predict the thermal performance of MHEs is developed.
- •
The model considers the effects of both axial/radial conduction and heat leakage.
- •
The axial conduction deteriorates the MHE performance at low mass flow rate.
- •
The effects of the axial conduction via the outer wall are important.
