Summary: In order to improve the energy density of lithium-ion batteries (LIB) and meet consumer demands for electric transportation, it is necessary to increase the overall size of the battery cells and decrease the share of inactive materials. However, this trend presents challenges in the electrolyte filling process due to increased wetting distance and decreased void volume. Numerical simulation and optimization offer a promising solution to reduce costs and ensure quality during battery production.

Summary: This paper proposes an improved Hybrid Particle Swarm Optimization (IHPSO) algorithm to find the near-optimal high-dimensional Latin Hypercube Design (LHD). The algorithm ensures population diversity through comprehensive learning, solves the oscillation problem of the PSO algorithm using the Minimum Point Distance (MPD) method, realizes the discretization of the PSO algorithm using the Ranked Ordered Value (ROV) rule, and executes local and global searches to find the near-optimal HLHD. Comparisons demonstrate the superiority of the proposed method compared with existing algorithms in obtaining the near-optimal HLHD.

Summary: This article provides a brief review of methods in design of experiments and criteria to determine space-filling properties of a set of samples. It introduces an adaptation to the strata creation process in Latin hypercube sampling, which solves the curse of dimensionality issue in sampling. The proposed approach places samples closer to design space boundaries, leading to more efficient sampling for high-dimensional optimization problems.

Summary: Computer experiments require space-filling designs. A new space-filling criterion has been proposed to assess designs on subregions of different sizes. This article introduces a projection space-filling criterion and provides examples and simulations to demonstrate its effectiveness. Additionally, optimal space-filling designs under the proposed criterion are considered.

Summary: This study proposes a multi-objective optimization approach to design a steam methane reforming (SMR) reactor and maximize the efficiency of the hydrogen production process. Only 50 iterations were performed, identifying three Pareto optimal designs with significant reactor size reductions and slight variations in process efficiency compared to the reference case. The results offer practical insights for planning on-site distributed hydrogen production systems and demonstrate the possibility of increasing overall process efficiency with a reduced reactor size.

Summary: The paper presents a new methodology to support sail designers in evaluating and optimizing downwind sail performance and manufacturing, using numerical methods and a newly developed fluid-structure interaction program to study different types of sails under various sailing conditions. A case study of a small sailing yacht's gennaker is used to demonstrate the methodology, and an analytical formulation for calculating sail corner loads is proposed based on numerical results. The novel methodology could potentially enable the widespread and effective use of numerical methods in yacht sail design and manufacturing.

Summary: A new fluid heater based on BCET was proposed in this paper, with fully-dimensional thermo-fluid analysis implemented to achieve more uniform and effective heat transfer to temperature-sensitive working fluids. Through geometry optimization with internal baffles, the uncontrolled temperature excess was significantly reduced, while the pressure drop across the flow device was also lowered.
