Design of Industrial Product with Curved Cavity Based on Lattice Boltzmann Method

Abstract

This paper aims to explore the design method of curved cavity industrial products based on lattice Boltzmann method. Lattice Boltzmann method, as a mesoscale numerical simulation method, can effectively simulate complex fluid dynamics behavior and provide a new idea for the design of curved cavity. By constructing a reasonable lattice model and collision operator, the flow characteristics of the fluid in the curved cavity can be accurately described, and then the geometry and size parameters of the cavity can be optimized to meet the needs of specific industrial applications. Taking the triple-period minimal surface as an example, its application in the pneumatic soft linear driver shows that the design based on lattice Boltzmann method can realize the pure single-axis linear drive, with the performance of "0 Poisson's ratio", large strain and strong load capacity. In addition, the method can also be used to predict the equivalent thermal conductivity of composite materials, which provides theoretical support for the application of curved cavity in thermal management and other fields. The research results show that the curved cavity design method based on lattice Boltzmann method has high accuracy and efficiency, and can provide strong technical support for the innovative design of industrial products, and has broad application prospects.
