离散颗粒 meaning in English
discrete particle
Examples
- A discrete particle motion - collision decoupled model was established in which particle collision was modeled by means of dsmc method
本文建立了离散颗粒运动-碰撞解耦模型,模型中应用dsmc方法模拟颗粒间的碰撞过程。 - Discrete particle models can be classified into deterministic method and stochastic method in accounting for the particle collisions
在离散颗粒模型中,根据对颗粒间碰撞过程的处理方法的不同可分为确定性模型和随机性模型。 - In the industrial process the material in the hopper always contains some water . with the aid of liquid bridge model , dem ( discrete element method ) and mathematical models , this paper firstly simulates the flow of wet particles in a hopper to study the influence of liquid bridge on the flow patterns and flow rate
针对这一情况，本文通过引入液桥力模型，结合离散颗粒法( dem ) ，首次用计算机模拟了料仓中湿颗粒的流动，研究了液桥力对料仓内颗粒流动形态以及质量流率的影响。 - Based on the thoroughly review and summary in the progress history of the multiphase flows researching in recent fifty years , the thesis was made an advanced discussion on the wide foreground of the multiphase flows " study and application , and clarified some concept of multiphase flows " study . take gas - solid two - phase flows for example , the thesis discussed and classified the theoretical model of multiphase flows " study , that is continuum model , discrete particle model and pseudo particle model , and made a deep and detail discussion on the foundation , advantage and disadvantage about the three physical model . the thesis considered that all the mathematics models of the multiphase flows " study are based on the three physical models
本文在系统、全面地回顾和总结近五十年来多相流研究发展历史的基础上，进一步论述了多相流研究和应用的广阔前景；澄清了多相流研究中存在的一些模糊概念；以气固两相流研究为例，对多相流研究的各种理论模型进行了系统的分析、归纳和分类，从而把气固两相流研究的物理模型按其刻划的尺度和属性分为三类，即：连续介质模型( continuummodel ) 、离散颗粒模型( discreteparticlemodel ) 、流体拟颗粒模型( pseudoparticlemodel ) ，并对三类物理模型赖于存在的基础、长处和存在的问题进行了深入的分析、讨论；同时指出，多相流研究的各种数学模型都是建立在以上三类物理模型的基础上的，从而对各种数学模型的实质、优缺点和今后发展方向有了清晰的了解。 - Recently , discrete particle model in which particles are directly tracked was paid widely attention due to the great development of computer hardware . in this model , gas phase is treated as continuous medium , and particle phase is treated as the discrete system . because particle movement is investigated in the particle - level , the multi - scales structure of fluidized bed can be simulated in both particle - scale and macro - scale
近年来,由于计算机硬件的飞速发展,直接对颗粒进行跟踪的离散颗粒模型得到了广泛的关注,此类模型将流体相处理为连续介质,颗粒相处理为独立的离散体系,由于它对颗粒相运动进行的是颗粒层次的分析,因而可以从颗粒尺度与宏观尺度模拟流化床气固两相流的多尺度结构。
