Microreactors have the advantages of high heat and mass transfer efficiency, strict control reaction parameters, easy amplification, good safety performance, been widely used in various fields such as chip manufacturing, fine chemicals, biomanufacturing. However, narrow microchannels microreactors often become filled with catalyst particles, leading to blockages. To address this challenge, study proposes a multiphase flow model based on lattice Boltzmann method (LBM) investigate dynamic changes during bubble collapse process temperature distribution regularities. Based developed three-phase dynamics model, delves into shock evolution analyzes Then, patterns under different particle density conditions are explored. The found that action wave, stable structure liquid film is destroyed, deforms collapses. At moment collapse, energy rapidly transferred from potential kinetic field. Subsequently, converted pressure waves. This results rapid generation extremely field, creating high-velocity jets intense turbulent vortices, which can enhance effects flows. certain phenomenon will be formed at region relatively chaotic random. waves generated significant impact motion trajectories while influence high-density particles small. offer theoretical basis for understanding mechanisms flow. Moreover, these findings practical implications advancing technologies industrial applications, including manufacturing chemical transport.

The toothless oil stirring disk is vital in modern transmission technology, particularly fields like aviation, aerospace, and nuclear power, significantly impacting equipment performance. Oil-stirring lubrication widely used internal systems due to its simplicity high reliability, but oil-stirring losses during contribute increased system temperatures, affecting lifespan Accurate simulation of the two-phase flow process high-speed disks crucial for extending service life. This paper proposes a dynamic modeling approach disks, integrating volume fluid (VOF) model RNG k-ε turbulence model, alongside spring smoothing mesh reconstruction techniques. explores distribution high-speed, pans, investigating effects different pan speeds heights on Results indicate that speed height are key improving efficiency. At speeds, centrifugal force gravity cause lubricating detach from surface, continuing splash inertia. 3200 r/min an level 20 mm, stable film forms gearbox. Higher generate greater turbulence, enhancing effectiveness. findings offer theoretical insights support gearbox design optimization aerospace similar fields.

The gear transmission system occupies a core position in mechanical equipment due to its numerous advantages such as high efficiency, reliability, and long durability, making it an indispensable key component. Investigating the distribution mechanism of two-phase flow field systems optimization design strategies is crucial for enhancing efficiency reliability gearboxes. This paper couples Lattice Boltzmann Method (LBM) with Large Eddy Simulation (LES) construct dynamic modeling solution method suitable lubrication high-speed gears baffles. objective explore characteristics Based on LBM–LES coupled model, this sets up model field. By conducting detailed analysis evolution process gearbox presence baffles, study reveals changing patterns dynamics under different velocities configurations mixing components. research findings indicate that when radial speed reaches 8 m/s, stable oil film can be formed surface, which ensuring smooth operation reducing wear. Additionally, has been confirmed larger baffle diameters hole effectively increase enthalpy fluid, thereby optimizing energy transfer thermal performance. However, noted diameter not always better; exceeds certain limit, performance improvement effect gradually diminishes, indicating existence optimal value. baffle, dissipation fluid within controlled, improving management These provide valuable references high-tech fields aviation aerospace. They help relevant technicians gain deeper understanding complex mechanisms involved process, allowing more efficient reliable systems, entire system, promoting progress development related technological fields.
