The main research interest is “Liquid Impingement Erosion Modeling”. The main objective of the current study is to quantify the impact of liquid droplets onto solid surfaces at high velocities. In order to model the interfacial flow in the fluid region which contains both liquid and gas phases Volume of Fluid Method is used. The droplet deformation is precisely captured upon impact within typical impingement velocity range of 100-500 m/s. In this regard, incompressible Volume of Fluid solver is used for low impact velocities and a compressible model is implemented at high impingement velocities. In addition, the solid substrate is modeled with Finite Element Method. A novel Fluid-Solid Interaction Model is developed that couples the gas-liquid interfacial model with the structural solver utilizing the two-way coupling approach. The coupling between fluid and solid is achieved by using the stress continuity on the fluid-solid interface and no-slip velocity condition. The pressure field in the fluid domain and the stress field in the solid domain are obtained simultaneously by solving coupled fluid and solid equations. The effect of the fluid compressibility on the generated pressure build-up in the liquid and the resulting stress in the solid is investigated.
