In this paper, the evaporation numerical model of droplet impinging on tubular wall with different wettability is established based smoothed particle hydrodynamics (SPH) method. The liquid phase mass fraction introduced and integrated merging technique to address change processes effectively. flow spreading heat transfer accompanying during impact a are simulated. Meanwhile, five walls prepared by sanding method surface active material modification. corresponding contact angles 11°, 36°, 58°, 78°, 112°, respectively. experimental study impacts conducted. reliability validity SPH verified comparing simulation results results. dynamic process droplets impacting simulated, effects wettability, temperature, Weber number further discussed explored. It found that poor hinders discourages process. factor increases temperature number. However, increase in promotes more significantly than tube temperature. Enhancing increasing enhancing beneficial liquid.
