摘要

提出了一种社会力(SF)模型来模拟烟雾扩散过程中行人的疏散情况。采用带源项的平流扩散法描述烟雾的传播过程。它被纳入到SF模型中。模型中的导航场由Eikonal方程解的负梯度决定。这取决于行人和烟雾密度。在有多个出口的室内进行了数值实验，并给出了实验结果。

A Social Force Model for Pedestrians’ Movements Affected by Smoke Spreading

A social force (SF) model is proposed to simulate the egress of pedestrians while smoke is spreading. The advection-diffusion with source term is used to describe the propagation of smoke. It is incorporated into the SF model. The navigation field in our model is determined by the negative gradient of the solution of the Eikonal equation. It depends on the pedestrian and smoke density. Numerical experiments are performed in a room with multiple exits, and their results are shown.

期刊介绍： Modelling and Simulation in Engineering aims at providing a forum for the discussion of formalisms, methodologies and simulation tools that are intended to support the new, broader interpretation of Engineering. Competitive pressures of Global Economy have had a profound effect on the manufacturing in Europe, Japan and the USA with much of the production being outsourced. In this context the traditional interpretation of engineering profession linked to the actual manufacturing needs to be broadened to include the integration of outsourced components and the consideration of logistic, economical and human factors in the design of engineering products and services.
