Abstract
In this paper, a class of efficient Monte Carlo methods based on weighted particle strategies for solving the coagulation population balance equation is presented. The adjustable coagulation resolution strategy is developed from probabilistic coagulation theories for general conditions. The particle reconstruction scheme accelerates simulations and reduces errors. Three components of the methods have been verified and validated against several benchmark coagulation scenarios with analytical solutions and a conventional constant-number method. The two methods, using stepwise-constant and size-dependent coagulation resolution, offer superior performance to the constant-number method in resolving regions with large and rare particles and higher-order moments without sacrificing computational efficiency. Moreover, the computation precision of both methods is significantly higher than the conventional methods, as the proposed method’s precision is proportional to the square root of the total number of coagulation events rather than being dependent on the computational particle number used by conventional methods.
期刊介绍:
The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide.
The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them.
Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
