Flow In Classroom Research Articles

Modeling and simulating the matching behavior of pedestrian flow at training school during the pickup period after class

Training schools widely exist in China and congestion occurs during the pickup period. However, most researches focus on investigating the pedestrian flow in classroom. In this paper, we study the adult–child matching behavior and each pedestrian’s motion (including child and adult) at a training school during the pickup period. Based on the scenario at the training school, and the features of children’s and adults’ motions, we design three strategies to describe the adult–child matching behavior, and then incorporate the matching behavior into a CA (cellular automaton) model and propose an extended CA model to study each pedestrian’s motion under each strategy during the pickup period. The numerical results indicate that each strategy has great effects on the matching behavior and the evacuation efficiency during the pickup period. The results can help administrators to design effective evacuation strategy at training school during the pickup period (especially when an emergency occurs).

Thermal energy flow modelling in a typical university classroom

In order to develop solutions for reducing energy consumption, an evaluation was made of the Civil Engineering Department building in the Isfahan University of Technology (IUT). As a part of this analysis, governing equations of mass, momentum and energy transport were used to model the heat flow in a typical classroom. The model was developed using finite element numerical method. The results of the simulation include temperature profiles and air flow streamlines. Some inefficiencies were observed due to the facilities set-up in the classroom. These inefficiencies could lead to students' discomfort. In order to improve the classroom living conditions, some practical recommendations were proposed. These suggestions consisted of guidelines for thermal isolation and air conditioners' locations. The numerical simulation model of the heat flow in the classroom suggests that the changes would make it a more comfortable place for its students.
