Numerical simulations of flow and heat transfer have been performed for flow over surface roughness.
- ass="label">•
The surface roughness influence on fluid flow and heat transfer has been investigated.
- ass="label">•
The lattice Boltzmann model has been used for energy transport for this simulation.
- ass="label">•
It has been found that in the presence of the surface roughness there is heat transfer enhancement.
- ass="label">•
The mechanism which causes this heat transfer enhancement is reviled.
