Abstract The influence of dynamic contact angle on flow boiling in vertical ducts is investigated based on the phase-change lattice Boltzmann method (LBM). To verify the correctness of the model, the surface tension of bubbles is calculated by the Laplace law and compared with the actual values. The influence of different contact angle on flow boiling is discussed. The mechanisms of bubble growth time and bubble waiting time on different contact angle surfaces are discussed. The heat transfer coefficient of different surfaces is investigated. The simulation results show that the boiling heat transfer characteristics on hydrophilic surface is better than that on hydrophobic surface.
