Abstract: | A new lattice Boltzmann model is presented for the simulation of heat transfer in near-critical fluids. Fluid layer between
two horizontal plates heated below near the thermodynamic critical point is simulated by the model. The spatial and temporal
evolution of the temperature field is analyzed. It is demonstrated that the model can describe accurately the piston effect
induced heat transfer at the piston effect timescale. |
