Practical application of Computational Fluid Dynamics (CFD) using COMSOL Multiphysics and Wolfram Mathematica

Shynggys Sariyev, Ulan Magzam, Damilya Askarbekova

This report delves into the practical application of Computational Fluid Dynamics (CFD) by simulating viscous channel flow through a sudden contraction in the laminar flow regime. The simulations were conducted using two distinct software platforms: Wolfram Mathematica and COMSOL Multiphysics. The primary goal is to compare the procedures and results obtained from each software, providing a deeper understanding of CFD principles and emphasizing the importance of validating simulation outcomes.

Laboratory Experimental Datasets on Route-choice Games

Hang Qi, Zhengbing He, Ning Jia

Total 312 participants in approximately equal proportions of males and females were invited to participate the decision-making experiments for the payoffs that were contingent on their performance. The participants were randomly assigned to 17 groups and they were required to make DTD route choices with no mutual communication. The following eight DTD scenarios with the same origin-destination (OD) pair were set.

• Scenario 1 was the baseline scenario containing a symmetric two-route network.
• Scenarios 2-5 extended Scenario 1 by using asymmetric two-route networks and different cost functions to investigate subject’s route choice behaviors under different cost feedback.
• Scenarios 6-7 employed asymmetric networks with three routes to observe more complicated route choice behavior.          •
Scenario 8 extended the configuration to non-linear cost functions and different group sizes (24 subjects per group in Scenario 8, while 16 in others), which would demonstrate the robustness of the proposed theoretical model.

Vehicle and charging scheduling of electric bus fleets: a comprehensive review

Le Zhang, Yu Han, Jiankun Peng, Yadong Wang

Purpose — Transit electrification has emerged as an unstoppable force, driven by the considerable environmental benefits if offers. Nevertheless, the adoption of battery electric bus is still impeded by its limited flexibility. The constraint necessitates adjustments to current bus scheduling plans. To this end, this paper aspires to offer a thorough review of articles focused on battery electric bus scheduling.

Design/methodology/approach — We provide a comprehensive review of 42 papers on electric bus scheduling and related studies, with a focus on the most recent developments and trends in this research domain.

Electric Vehicle Trip Energy Consumption Data

Yang Liu

The data consists of normal driving records for dozens of private cars over several months (from June 5, 2015 to June 30, 2016), with a sampling frequency of one minute. The basic specifications of the vehicles are as follows: Roewe E50 is a pure electric vehicle, weighing 1080 kilograms. It is equipped with a 22.4 kWh battery pack, and is reported to have a driving range of 170 kilometers. The raw data has been preprocessed and denoised, resulting in a final dataset containing 10,000 trips. This dataset offers substantial potential for reuse in research and analysis focused on electric vehicle energy consumption. Researchers, engineers, and policy makers can leverage this data to understand patterns, develop optimization algorithms, and inform energy-efficient practices. The dataset adheres to all applicable legal requirements. All sensitive information has been removed, and the data has been preprocessed to ensure confidentiality. There are no known legal or ethical obstacles to its use.

Training and Application Code of the MDP Driving Policy in Highway

Yang Guan

The dataset comes from the paper "Markov probabilistic decision making of self-driving cars in a highway with random traffic flow: a simulation study" and mainly consists of three parts:

1. The "policy_training" folder, which includes the code used for training driving strategies in the highway scenario mentioned in the paper. The main function is "main_v3.cpp," and the functionality is implemented in the file "f_define_v3.cpp." Additionally, "to_strategy.m" exports the trained strategy as a state-action table for application, and "FIGURE.me" visualizes this table.

2. The "policy_application" folder contains "test.py" as the main file, which uses "MdpModel.py" to call the state-action table from the "Strategy" folder and visualizes it through "MdpModel.py." The "Map" and "Vehicle" folders store visualization elements.

3. The third part is a video of the visualization results named "simulation_demo.avi."
