摘要: Abstract In the present paper combination of three-dimensional isothermal and two-dimensional non-isothermal Lattice Boltzmann Method (LBM) are employed to simulate nucleate pool boiling phenomenon. order validate proposed model, rising bubble phenomenon is simulated afterward process investigated by employing a function for heat transfer. The investigation compared with other numerical works found be in very good agreement. effects parameters including contact angle, flux heater length on departure dimensionless time diameter studied. results show that increases due increase angle decrease gravity force. Formation, motion breakup bubbles also as force flux. Furthermore, it worthwhile pointing out increasing has more effect comparison growth. Transient regime shown small vanishing while upward at high
