观点:耗散粒子动力学

Perspective: Dissipative Particle Dynamics

Pep Español, Patrick B Warren

摘要:

耗散粒子动力学(DPD)是为解决复杂流体和一般软物质中的介观问题而发展起来的一类模型和计算算法。它基于粒子的概念,这些粒子代表所研究系统的粗粒度部分,因此可以达到微观模拟无法达到的时间和长度尺度。自25年前引入以来,该方法在概念上得到了完善。这种观点调查的主要概念改进的原始DPD模型,随着其微观基础,并讨论了在该领域的突出挑战。我们总结了一些最近的进展,并提出了未来发展的途径。

英文摘要:

Dissipative particle dynamics (DPD) belongs to a class of models and computational algorithms developed to address mesoscale problems in complex fluids and soft matter in general. It is based on the notion of particles that represent coarse-grained portions of the system under study and allow, therefore, to reach time and length scales that would be otherwise unreachable from microscopic simulations. The method has been conceptually refined since its introduction almost twenty five years ago. This perspective surveys the major conceptual improvements in the original DPD model, along with its microscopic foundation, and discusses outstanding challenges in the field. We summarize some recent advances and suggests avenues for future developments.
