- •
CFD-DEM is extended for heat transfer of ellipsoidal particles.
- •
Particle shape significantly affects bed effective thermal conductivity.
- •
Ellipsoids have lower convective heat flux but higher conductive heat flux.
- •
Prolate particles have larger heat transfer coefficient than other particle shapes.
