Unification of Lagrangian staggered-grid hydrodynamics and cell-centered hydrodynamics in one dimension
Xihua Xu
This paper focuses on the novel scheme to unify both Lagrangian staggered-grid and cell-centered hydrodynamic methods in one dimension. The scheme neither contains empirical parame…
Computing Overlaps of Two Quadrilateral Mesh Of the Same Connectivity
Xihua Xu, Shengxin Zhu
An exact conservative remapping scheme requires overlaps between two meshes and a reconstruction scheme on the old cells (Lagrangian mesh). While the are intensive discussion on re…
Non-linear Dynamics, Emergent Behaviors and Controlled Expansions: Towards Effective Modeling of the Congested Traffic
Bo Yang, Xihua Xu, John Z. F. Pang +1
We propose a framework for constructing microscopic traffic models from microscopic acceleration patterns that can in principle be experimental measured and proper averaged. The ex…
Cluster Statistics and Quasisoliton Dynamics in Microscopic Car-following Models
Bo Yang, Xihua Xu, John Z. F. Pang +1
Using the optimal velocity (OV) model as an example, we show that in the non-linear regime there is an emergent quantity that gives the extremum headways in the cluster formation,…
