A stabilized local radial basis function collocation method (LRBFCM) is proposed to simulate the electrochemical 3D double-nozzles printing process. The fluid flow described by Navier-Stokes equations is discretized using a forward Euler-method. Background fictitious grids are used to enhance the stability of the LRBFCM in solving the fluid flow. The accuracy of the proposed method is validated through corresponding experiments.
In this work, a stabilized local radial basis function collocation method (LRBFCM) is proposed to simulate the electrochemical 3D double-nozzles printing. A forward Euler-method is proposed to discretize time in the fluid flow described by Navier-Stokes (NS) equations. The background fictitious grids or meshes are employed to enhance the stability of the LRBFCM in solving the fluid flow. The details of the LRBFCM for simulating the pressure and velocity fields of the electrolyte during the electrochemical 3D printing process are introduced. The accuracy of the proposed method is validated by corresponding experiments, and good agreement can be observed between the numerical results and the experimental measurements.
