Direct Numerical Simulations of Pool Boiling Heat Transfer and Thermal Responses Inside the Heater by Lattice Boltzmann Method

• 摘要：

  Direct numerical simulations of pool boiling heat transfer are performed by the pseudopotential liquid-vapor phase change lattice Boltzmann model. Boiling curves from natural convection regime to film boiling regime and thermal responses inside the heater are numerically obtained. It is found that the simulated critical heat flux (CHF) agrees reasonably well with existing analytical models. In addition, simulated boiling heat fluxes in film boiling regime are also in good agreement with classical solutions. The model is thus quantitatively validated. Simulation results demonstrate that temperature distribution at the top of heater surface is nonuniform, especially in CHF point and transition boiling regime.
