摘要:
该文研究了平板边界层中的双峰谱分布颗粒系统的演变过程。用层流平板边界层的解析解(Blasius解)来给出流场分布。对于颗粒相,利用了一种新的矩方法模型,即二元泰勒展开矩量法(BTEMOM),描述对流、扩散和凝并等动力学过程。验证了新模型对双峰颗粒系统的效率和精度。在边界层的强剪切作用下,最终研究了特征参数如数密度、标准偏差以及几何体积。
Abstract:
In this paper,the evolution of the bimodal particle system in a flat-plate boundary layer is studied.The flow field distribution is given by the Blasius solution.For the particle phase,a new method of moment，namely binary Taylor expansion method of moments(BTEMOM), was utilized to describe the dynamic processes such as:advection,diffusion and coagulation.The efficiency and accuracy of the new model to the bimodal particle system are verified. Under the strong shearing effect of the boundary layer,the characteristic parameters such as the number density,the standard deviation,and the geometric volume are finally studied.
