Abstract：

The　precision　of　ultrasonic　flowmeter　is　mainly　depending　on　ultrasonic　path　adaptability　for　velocity　profile　of　pipe,　especially　for　the　special　cases,　such　as　ultrasonic　flowmeter　located　near　the　elbow　of　pipe.　In　this　paper,　the　flow　fields　of　some　typical　pipes　were　numerically　calculated　with　commercial　CFD　software,　and　the　velocity　profiles　in　different　section　of　pipe　were　investigated.　Based　on　the　simulated　velocity　profile,　flow　rate　in　special　section　of　the　double　bend　pipe　was　measured　using　different　ultrasonic　path　configuration　methods,　such　as　Gaussian-path,　Jacobian-path　and　diametral-path.　According　to　the　error　of　the　measured　flow　rate,　it　is　easy　to　get　the　optimal　layout　of　ultrasonic　path　for　the　particular　velocity　profile.　It　is　proved　that　the　numerical　simulation　of　flow　field　is　useful　for　the　optimization　of　the　ultrasonic　paths　of　flowmeter.　©　2010　IEEE.
