It then passes into an aerodynamically designed eff user (cone) that accelerates the air in a linear manner before it moves through the working section.<\/li>\n<li>Finally it passes through a diffuser, then into the variable speed axial fan. The grille protects the fan from damage by loose objects. The air leaves the fan, passes through a silencer unit and then back out to atmosphere.<\/li>\n<li>The speed of the axial fan (and therefore the air velocity in the working section) is controlled by an electronic drive control in the separate On\/Off unit mounted on the tunnel\u2019s associated instrument frame along with other ancillaries.<\/li>\n<\/ul>\n<p><em><span style=\"text-decoration: underline;\">Learning Outcomes:<\/span><\/em><\/p>\n<ul>\n<li>Flow past bluff and streamlined bodies with pressure and velocity observations in the wake<\/li>\n<li>Investigations into boundary layer development<\/li>\n<li>Influence of aspect ratio on aerofoil performance<\/li>\n<li>Pressure distribution around a cylinder under sub and super-critical flow conditions<\/li>\n<li>Study of characteristics of models involving basic measurement of lift and drag forces<\/li>\n<li>Study of the characteristics of three-dimensional aerofoils involving measurements of lift, drag and pitching moment<\/li>\n<li>Study of the pressure distribution around an aerofoil model to derive the lift, and comparison with direct measurements of lift<\/li>\n<li>Drag force on a bluff body normal to an air flow<\/li>\n<li>Flow visualisation<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Product Code: AF1450<\/p>\n","protected":false},"featured_media":4412,"template":"","meta":[],"product_cat":[31,917],"product_tag":[],"_links":{"self":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product\/4414"}],"collection":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media\/4412"}],"wp:attachment":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media?parent=4414"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_cat?post=4414"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_tag?post=4414"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
