根據e-wind中線上計算流體力學架構的初步理念，本研究建置了一線上行人風場評估系統：使用者將透過系統網站直接繪製欲測試的建築物模型，系統會將使用者輸入的各項資訊轉換後，建立計算流體力學的輸入檔，接下來將此輸入檔通過伺服器的操控，進行線上計算流體力學軟體的運算。經過運算後系統會讀取計算的輸出檔數據、將數據繪製行人風場剖面的風速等值線圖，供使用者觀察建築物週遭的風場趨勢。系統也會提供直接評估法表格，供使用者進行行人風場舒適度的狀態評估。最後，使用者也可以將數據資料壓縮與下載存檔至個人電腦中，並安裝Smokeview軟體做更進一步的觀察。 The concept of the thesis derived from the project, e-wind, which was proposed by professors of Tamkang University Wind Engineering Research Center. This program aims at providing wind engineering computing, data analysis and other information on the Internet; one of them is an expert system of online pedestrian wind comfort assessment.
It is crucial and necessary to establish a friendly interface and tabular with graphical presentation for common user. Therefore, how to integrate the concept of computational fluid dynamics (CFD) into informational and networking is the main objective of this study. If we can establishment of the CFD analysis model through a browser and perform remote CFD software that discern the trends of wind speed, it not only dramatically reduce the time spent by the architectural design and the ambient wind field assessment, but also allows students easy to learn knowledge in this area.
According to the fundamental concept of the e-wind for online computational fluid dynamics framework, the study set up an online pedestrian comfort assessment system:, The users will be drawn directly through the website for the test model of the building, system will enter the information into a CFD input file. Followed by this input file to online CFD computing by the server manipulate, then system will read the output data of operation after calculated, and draw a wind speed contour map, and the users can view the wind field trend arround the buildings by the pedestrian wind field profile. System will also provide Absolute Assessment form for the users to assessment. Finally, the user can compress data and download it to PC, and install Smokeview for further observation.
