本實驗利用不銹鋼儲水槽提供一穩定的加壓水源,配合電磁閥產生類似於心臟輸出的脈衝流。測試段是使用三種同長度但不同材料的彈性管作為模擬的血管模型進行實驗,由不銹鋼儲水槽提供的脈衝流經血管模型傳至背壓儲水槽進行平均流量的量測。另外利用微型麥克風進行彈性管管徑波形的量測,將量取的波形訊號與彈性管的流量做比較分析後發現,流經彈性管之脈衝流的平均流量大小和脈衝頻率與彈性管管徑振動之主頻的相位有關,在脈衝流之平均流量相對於理論值多時,脈衝頻率之相位正弦值與彈性管自然頻率之相位正弦值皆為正,反之則皆為負。亦即脈衝頻率與彈性管產生共振時,脈衝流之平均流量相對於理論流量會有增加或減少的現象,此實驗結果可以證明使用不同材料特性的彈性管,配合不同的脈衝頻率可以有不同的平均流量,即可以利用脈衝頻率控制其流量。
A stable water head is provided by a pressurized water tank and a sinusoidal electric valve is used to generate the pulsed jet stream which is similar to the heart blood flow. Three kinds of elastic tubes with the same length of different materials are used to model blood vessel. The pulse of water jet from the pressurized water tank flows through these tubes into a cistern for the measurement of average flow rate. A microphone on the tube surface was used to measure the surface wave of these elastic tubes. The frequency analysis of the wave signal in accordance with various of the water flow rates of these elastic tubes has been done. It has been observed that the average pulsed flow rate is larger than the theoretical flow rate, when both of the phases of pulse frequency and the natural frequency of elastic tube are positive and vice versa. Thus, the average flow rate is being increased or decreased owing to the resonance of the pulsed flow with these elastic tubes. Therefore, not only the different material properties of the elastic tubes but also the different on pulsed flow frequency can bring about distinctive flow rate.
