Pedestrian Flow Characteristics Studies: A Review
Transport Reviews, 2015Co-Authors: Ankit Gupta, Nitin PundirAbstract:Out of total trips made, the share of walking is considerable enough to warrant giving more emphasis to pedestrian Flow studies in order to incorporate them in integrated design of urban areas. Analyses of pedestrian Flow Characteristics constitute one of the foundations of urban traffic planning and this includes analyzing walking speed, Flow, density and space required by the ped- estrians. As pedestrian Flow Characteristics are a location-based phenomenon, various researchers have studied these locally. An extensive review of literature is undertaken for various existing studies on pedestrian Flow Characteristics under different traffic conditions and on different ped- estrian facilities in urban areas. These studies are focused on various parameters of pedestrian move- ment that are of fundamental importance in any pedestrian modeling approach. These parameters are pedestrian speeds and pedestrian speed–Flow–density relationships. These studies aim to cast light on the need to provide exclusive pedestrian facilities and to correct any deficiency in facilities provided to the pedestrians. The review highlights the lack of a global and detailed consideration of pedestrian behavior along entire trips in urban areas. A set of studies of pedestrian Flow Characteristics are discussed thoroughly and general suggestions for further research in the field are presented at the end.

Analysis and Optimization of Flow Characteristics of Steam Turbine Valve
Southern Power System Technology, 2010Co-Authors: Zhang HongfuAbstract:To solve the problems existing in the Flow Characteristics of turbine generator,and based on the analysis of steam distribution modes and influence of valve overlapping on the Flow Characteristics,this paper proposes a scheme of steps and methods for valve Flow experiments of turbine generator,and optimizes the parameters.The results show that the linearity of load demand-Flow function is good,the load and pressure are transiting smoothly through valve switchovering without obvious Flow inflection points as well.The application of the scheme in several power plants shows that the proposed method can quite accurately fit the experiment data of valve Flow Characteristics,and thus it is feasible.

The study of Flow Characteristics of curved microchannel
Applied Thermal Engineering, 2005Co-Authors: Wei-hua Yang, Jing-zhou Zhang, Huier ChengAbstract:Abstract Some curved microchannels with different curvature radiuses and geometrical dimensions were designed, and the Flow Characteristics of them were all tested. Based on the experiment results, different Flow Characteristics of them were obtained. The Flow Characteristics of the fluid in curved microchannels were numerically studied by the classical N–S equation, and the obvious difference between the results of the numerical calculation and the experimental results was found. In order to explain this kind of difference, introduced a roughness-viscosity model to the classical N–S equation, and it was found that the prediction of roughness-viscosity model was in agreement with the experimental data.

Empirical Relationships among Pedestrian Flow Characteristics in an Indoor Facility
Research Journal of Applied Sciences Engineering and Technology, 2014Co-Authors: Luthful Alahi Kawsar, Noraida Abdul Ghani, Anton Abdulbasah Kamil, Adli MustafaAbstract:Pedestrian Flow Characteristics are site and region specific. For developing a safe evacuation system for indoor facilities, pedestrian Characteristics on such facilities should be well understood. In this study, the findings of a study of pedestrian Flow Characteristics for level walkways and stairways inside a hall room type facility are described. The empirical relationships between different pedestrian Characteristics are presented mathematically as well as graphically. In addition, the free-Flow speeds of pedestrians for level walkways and stairways are observed, which is necessary to assess the pedestrian Flow Characteristics at high congestion. The comparison of the findings of current study with that of other previous studies on outdoor and different types of indoor facilities indicates the significance of this study. The relationships that have been established in this study could be used as guidelines for the development of evacuation models for hall room type facilities.
