Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

With rapid economic development and increase of population in Kaohsiung in recent years, it is ineluctable that buildings are built higher and bigger. In the metropolitan area, the air flow is hampered by the high-rise buildings, which are densely built in the same region, seriously affecting the air flow distribution. The environmental air flow is subject to the shape and the heights of buildings, once being impeded, it is likely to become swirling turmoil, “street wind”, which has high wind speed, or become “high-rise building wind”, caused by screen effect. All the above will alternate how outdoor air flows, causing inconvenience for the residence in the area.

To analyze and discuss this phenomenon, this research uses the high-rise building in Kaohsiung as its model, and adopts Computational Fluid Dynamics (CFD) flow simulation to simulate how air flows around high-rise buildings. The simulated factors include 1) south west wind in summer and north east wind in winter, 2) wind speed 1.91 m/s in summer and 1.66 m/s in winter, 3) different heights of buildings, which are 45m、60m、84m、150m.

This research uses Computational Fluid Dynamics (CFD) to analyze the climate in Kaohsiung, and utilizes A Research on The feasibility of Air Ventilation Assessment, conducted by The Chinese University of Hong Kong, as a guideline to evaluate the impact and the benefits of different periods of natural air ventilation may have on different heights of high-rise buildings. By doing so, the efficacy of natural air ventilation of high-rise buildings could be predicted and can serve as a guideline for designers and users on architecture design planning.
