R. Chu (ext:34138)<\/p>\n<blockquote>\n<p>1.Atmospheric Boundary Layer Wind Tunnel<\/p>\n<\/blockquote>\n<p>The atmospheric boundary layer wind tunnel is an open-circuit, low-speed wind tunnel designed to simulate atmospheric boundary layer flows, in which many civil engineering problems occur. For example, air pollution in the urban area, wind load on the high-rise building and suspending bridges all can be studied in this wind tunnel. Due to the fact that atmospheric boundary layer is usually much higher than the building immersed in it, the simulated boundary layer in the wind tunnel must be quite thick (the test section therefore should be large) in order for the model building to be of reasonable size.<\/p>\n<p>The total length of the wind tunnel is 29.2 m, test section is 18.5 m long, 3.1 m wide, and 2.1 m high. The ceiling of the test section is adjustable to Compensate for blockage when large models are used. Two turntables (diameter 2.0 m and 2.8 m) in the test section can be easily rotated to change the effective wind direction to the models. A 200 hp motor driving a 1.8 m diameter fan produces a top wind speed of 20 m\/s. The 1:4 contraction section contains honeycomb and four screens to produce a low-turbulence flow at the entrance of the test section. Vorticity generators at the entrance of the test section are used to create a thick boundary layer. An instrument carriage mounted on rails can three-dimensionally position the measuring sensors by remote control. A smaller wind tunnel (1.0 m long, 0.2 m wide, and 0.2 m high) is also available for the calibration of instruments and smaller scale studies.<\/p>\n<\/div><\/section><\/div><div class='av-flex-placeholder'><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-3z3e0f-2bef232369999b085d76433f92bb0e5b\">\n.flex_column.av-3z3e0f-2bef232369999b085d76433f92bb0e5b{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-3z3e0f-2bef232369999b085d76433f92bb0e5b av_two_fifth  avia-builder-el-10  el_after_av_three_fifth  el_before_av_hr  flex_column_table_cell av-equal-height-column av-align-top av-zero-column-padding  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-k8sc3j7d-fe27b5b8c5079aea8d8862bfc9a3aef8\">\n.avia-image-container.av-k8sc3j7d-fe27b5b8c5079aea8d8862bfc9a3aef8 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-k8sc3j7d-fe27b5b8c5079aea8d8862bfc9a3aef8 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-k8sc3j7d-fe27b5b8c5079aea8d8862bfc9a3aef8 av-styling-no-styling avia-align-center  avia-builder-el-11  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><a href=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e.jpg\" data-srcset=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e.jpg 314w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e-283x200.jpg 283w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e-260x185.jpg 260w\" data-sizes=\"(max-width: 314px) 100vw, 314px\" class='avia_image'  aria-label='1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e'><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-4473 avia-img-lazy-loading-not-4473 avia_image ' src=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e-283x200.jpg\" alt='' title='1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e'  height=\"200\" width=\"283\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e-283x200.jpg 283w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e-260x185.jpg 260w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u5927\u6c23\u908a\u754c\u5c64\u98a8\u6d1e.jpg 314w\" sizes=\"(max-width: 283px) 100vw, 283px\" \/><\/a><\/div><\/div><\/div><\/div><\/div><!--close column table wrapper.

For example, internal wave, ocean outfall, dispersion in stably stratified atmosphere all can be studied in this facility. The test section of the flume is 25.0 m long, 1.0 m wide and 1.0 m deep, with glass side walls to allow for flow visualization. A filling system, consisting of a 1.0 m by 1.0 m, and 1.5 m deep mixing tank, pipe lines at the flume bottom and pump, provides the capability of filling the flume with salt water layer by layer to the required stratification condition. Both linear and two-layer stratified flows can be generated in the flume. A towing carriage on the top of the water flume provides a mounting device for model. The carriage speed is continuously adjustable from 0 to 0.8 m\/s.<\/p>\n<\/div><\/section><\/div><div class='av-flex-placeholder'><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-3z3e0f-2bef232369999b085d76433f92bb0e5b\">\n.flex_column.av-3z3e0f-2bef232369999b085d76433f92bb0e5b{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-3z3e0f-2bef232369999b085d76433f92bb0e5b av_two_fifth  avia-builder-el-33  el_after_av_three_fifth  el_before_av_hr  flex_column_table_cell av-equal-height-column av-align-top av-zero-column-padding  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-k8sc3j7d-d849a7e79f497ae201569d40db5a49fa\">\n.avia-image-container.av-k8sc3j7d-d849a7e79f497ae201569d40db5a49fa img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-k8sc3j7d-d849a7e79f497ae201569d40db5a49fa .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-k8sc3j7d-d849a7e79f497ae201569d40db5a49fa av-styling-no-styling avia-align-center  avia-builder-el-34  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><a href=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd.jpg\" data-srcset=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd.jpg 261w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd-260x174.jpg 260w\" data-sizes=\"(max-width: 261px) 100vw, 261px\" class='avia_image'  aria-label='1.2.3\u62d6\u66f3\u6c34\u69fd'><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-4477 avia-img-lazy-loading-not-4477 avia_image ' src=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd.jpg\" alt='' title='1.2.3\u62d6\u66f3\u6c34\u69fd'  height=\"174\" width=\"261\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd.jpg 261w, https:\/\/www.cv.ncu.edu.tw\/wp-content\/uploads\/2020\/05\/1.2.3\u62d6\u66f3\u6c34\u69fd-260x174.jpg 260w\" sizes=\"(max-width: 261px) 100vw, 261px\" \/><\/a><\/div><\/div><\/div><\/div><\/div><!--close column table wrapper.
