- •
A new particle-scale oxygen uptake rate model with surface convection was built.
- •
More precise simulation results were obtained for manure–wheat straw composting.
- •
Surface convection accounts for 8.86% of the total heat contribution.
- •
Expanding the exchange-surface is suggested to benefit degradation.
