It shows that the adjacent synthetic jet flow field is affected by the phase - difference , amplitude and frequency of two actuators , and the synthetic jet is asymmetric and turning when they are working differently . the main reasons result with the asymmetry and the interaction between the two adjacent synthetic jets , leading to the formation of “ low pressure closed circumfluence region “ , which is also called entrainment field , and the synthetic jet turns to the region where the pressure is lower and the vorticity magnitude is higher 當兩相鄰激勵器處于不同工作狀態同時工作時,合成射流將發生偏轉,其主要機理是由于兩激勵器吸入和排出流體流動不同,使得兩列旋渦對不對稱,在兩列旋渦對之間存在“卷吸場”和壓強梯度,從而引起旋渦對向低壓側和強渦量區偏轉。

With experiments and theoretical analyzing , we find when the heat discharge is smaller than the entrainment limited , what influences the ability of heat - transmitting of work quality is the quantity of injection and dry limit fluid inventory , the optimum quantity of injection of the three working fluid is 8 ~ 14g ; and the delivering factor that transmission coefficient is determined by capillary limit , not the heat transmission ability of the thermal syphon . therefore , among the three working fluid , acetone is the best . low wind - speed has the obvious function in heat transmission of the thermal syphon 本文通過實驗研究和理論分析,認為在熱流量小于攜帶極限時,影響工質傳熱能力的是cpu重力熱管的充液量和其干涸極限,此次所實驗的三種工質,最佳充液量應當在8g ~ 14g ;傳輸因素主要決定普通熱管的毛細極限,而不是重力熱管傳熱能力的決定因素;三種工質中的最佳工質是丙酮;小風速時風速的變化對cpu重力熱管的傳熱有明顯的作用,但在風速大于1m / s以后,風速增加對于cpu重力熱管的傳熱能力的增加效果減緩。
