A three-dimensional venturi model was developed and analyzed in ANSYS Fluent. The study evaluated velocity and pressure behavior at throttle angles of 0 , 15 , 30 , and 45 . Results show that low throttle openings produce weak airflow acceleration and insufficient pressure drop. Increasing the throttle angle enhances velocity and reduces static pressure at the venturi throat. The 30  throttle angle provides the best balance between airflow acceleration and pressure distribution. Velocity and pressure contours at 30  show smooth flow with limited separation. At 45 , higher airflow is accompanied by increased turbulence and non-uniform pressure recovery. Flow separation and recirculation downstream of the throttle contribute to energy losses. Overall, the study identifies 30  as the optimum throttle angle for efficient venturi performance and improved air-fuel mixture formation.\u003c\/p\u003e","brand":"LAP Lambert Academic Publishing","offers":[{"title":"Paperback","offer_id":47570391728279,"sku":"9786209529177","price":4237.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9786209529177.webp?v=1774881753","url":"https:\/\/atlanticbooks.com\/products\/performance-analysis-of-carburetor-fuel-metering-in-si-engines-9786209529177","provider":"Atlantic Books","version":"1.0","type":"link"}
