hot-wire anemometer मीनिंग इन हिंदी

The paper introduces acquired air rate of flow in admission pipes and fluidity in cylinder on single cylinder or multi cylinder engines with hot - wire anemometer , and demarcation and adjustment method of measure values are provided
Reynolds numbers ( based on average velocity at passage inlet and hydraulic diameter of the passage ) are changing from 20000 to 80000 and the extraction ratios ( suction ratios , sr ) are changing from 0 . 30 to 0 . 60 for each test model . so the influences of reynolds numbers , suction ratios and etc . on the discharge coefficients and pressure loss characterist ics are also presented . flow fields of typical passages are visualized with the flow visualization techniques and measured with hot - wire anemometer
