It shows the conversion of statistical temporal mean values of turbulent flows into balance-based ones and the selection of averaged values in order to clarify which values experts should take into account for the solution for a special problem. Three examples with calculated or measured flow fields are described and evaluated: the exhaust casing of a low-pressure steam turbine, the stage of a radial-flow compressor and an axial-flow turbine. It is shown how mechanical and thermodynamic properties can be described properly for a one-dimensional flow. Comparisons are made with conventional representations and the significance of inhomogeneity characteristics is demonstrated. A demonstration software program for plane averaging is described and provided.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Balance-based averaging of inhomogeneous flow fields &#8211; Applications<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/din\/\"><b>DIN<\/b><\/a><\/td>\n<td>2019-04<\/td>\n<td>44<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":554604,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[264,447,2635],"product_tag":[],"class_list":{"0":"post-554592","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-17-120-10","7":"product_cat-27-010","8":"product_cat-din","10":"first","11":"instock","12":"sold-individually","13":"shipping-taxable","14":"purchasable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/554592","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/554604"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=554592"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=554592"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=554592"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
