## 1 Introduction  
Cavitation is a unique physical phenomenon occurring in a liquid, which is a perpetual research subject due to its specific dynamic effects [1; 2; 3]. Collapsing cavitation bubbles usually produce extreme physical phenomena, such as high velocities, high pressures and high temperature in partial areas. While a collapsing cavitation bubble is close to a solid surface, these physical phenomena cause serious damage to the surface of the material, which is called cavitation erosion. On the other hand, collapsing cavitation bubbles have been widely used in various applications, such as material surface modifications [4; 5; 6] and medical fields [7; 8; 9]. From these applications, we can extract a valuable and general issue, i.e., the investigation of the interaction between cavitation bubbles and a solid surface with different properties. Many research papers have discussed the interaction between a surface and a cavitation bubble from different perspectives, including the roughness of the surface, interfacial wettability, and surface tension. With their experiments, [PERSON] et al. studied the effects of nozzle inner surface roughness on the cavitation erosion characteristics of high-speed submerged jets [10]. Their findings showed that geometric characteristics of the surface have great effects on cavitation erosion intensity at standoff distances around or exceeding the optimum. [PERSON] et al. explored the controlled effect of ultrasonic cavitation on hydrophobic/hydrophilic surfaces [11]. They developed a selective control scheme of ultrasonic cavitation on metal surfaces with different hydrophobicities. Their findings from the experiments showed that cavitation prefers to dominate on hydrophobic surfaces due to the low nucleation barrier. Due to the limitations of the experiment, the microcosmic mechanism of interaction between the cavitation bubble and the solid surface was not discussed in their work. The lattice Boltzmann method (LBM), as a mesoscopic approach based on the kinetic Boltzmann equation, has been rapidly developed in recent years [12]. LBM has been employed in research on the interaction between the cavitation and surface of solid surface materials due to its convenience in multiphase and fluid-solid surface modeling [13]. In References [13], [PERSON] discussed the effects of wettability on cavitation inception using LBM. The study showed that the pseudopotential LBM was robust and efficient for predicting cavitation phenomena with surface wettability effects considered. It was also accurate enough for cavitation flow under different conditions. However, the above researchers' works do not involve the stage of the collapsing cavitation bubble, which is critical for the interaction between cavitation and the solid surface. The challenge of the simulation of the collapsing cavitation bubble near the solid surface is the stability of the lattice Boltzmann (LB) model. For the pseudopotential multiphase model [14], the stability is closely related to the thermodynamic consistency, and many efforts have been made for this issue [15; 16; 17]. Recently, [PERSON] et al. [18] studied the evolution of the collapsing cavitation bubble near a rigid boundary using LBM. They established a collapsing bubble model using an improved forcing scheme based on that of [PERSON] et al. [16]. The numerical results were compared with experimental results. [PERSON]'s research demonstrated that the pseudopotential multi-relaxation-time (MRT) LB could successfully simulate the collapsing cavitation bubble near the solid wall. However, there is no fluid-solid interaction added in the simulation model. In the present work, the pseudopotential MRT LB with the improved forcing scheme proposed by [PERSON] et al. [17; 19; 20] is applied to investigate the cavitation bubble collapse near the hydrophobic or hydrophilic surface. The fluid-solid interaction is adapted to the pseudopotential MRT LB to achieve the fluid-solid boundary.
