These 2D simulation results will compare the performance of these similar structures, each with the same area but slightly different shapes, thus shedding light on the aerodynamic properties of the sailfish-bill-like structures in viscous fluids. The LBM model will be established using the open source code on Palabos in C/C++ to create the simulation channel and the obstacle, as well as to capture the fluid behavior on a mesoscopic scale and convert mesoscopic variables to macroscopic ones for data visualization and comparison purposes.application/pdfengCopyright is held by the author, unless otherwise indicated.
