유동 가스 온도 변화에 따른 삼각 분리 막대형 차압 유량계 특성 연구 = A Study on Characteristics of a Triangular Separate Bar Differential Pressure Flow Meter according to Variation of Gas Flow Temperature

다국어 초록 (Multilingual Abstract)

Differential pressure flow meters which have a shape of triangular separate bar (TSB) were tested for investigating the flow characteristics of the flow meters with varying the temperature of the gas flow. Three kinds of the triangular separate bar flow meters whose aerodynamic angles are different one another are used. The mass flow rate of the flow meters are evaluated using non-dimensional parameter which includes the gas temperature, exhaust gas pressure, the differential pressure at the flow meters and atmospheric pressure. A burner system was used for raising the gas temperature. The burner system was operated with varying the air/fuel ratio by controlling both the fuel injection rate at the fuel nozzle and air flow rate from a blower. An empirical correlation between mass flow rate at the TSB flow meter and the non-dimensional parameter was obtained. The empirical correlation shows linear relationship between the mass flow rate and the non-dimensional parameter H. Also, the mass flow characteristics at the TSB flow meter was affected by the gas temperature.
