【摘要】：在P為3~8 MPa的壓力范圍內(nèi),以截面尺寸為50 mm×2 mm的矩形并聯(lián)雙通道為實(shí)驗(yàn)本體,開展靜止條件和傾斜、起伏、搖擺等運(yùn)動(dòng)條件下的密度波流動(dòng)不穩(wěn)定性實(shí)驗(yàn)。在時(shí)域和頻域內(nèi),分析運(yùn)動(dòng)條件對(duì)流動(dòng)失穩(wěn)現(xiàn)象的影響。通過對(duì)比靜止條件下的實(shí)驗(yàn)結(jié)果,分析運(yùn)動(dòng)條件對(duì)流動(dòng)不穩(wěn)定邊界的影響。最后基于實(shí)驗(yàn)數(shù)據(jù),擬合了流動(dòng)不穩(wěn)定邊界的經(jīng)驗(yàn)關(guān)系式。
[Abstract]:In the pressure range of P 3~8 MPa, a rectangular parallel double channel with a cross section size of 50 mm x 2 mm is used as the experimental body to carry out the density wave flow instability experiment under the conditions of static condition and tilt, fluctuation and swaying. In the time and frequency domain, the effect of the motion condition on the instability of the convective motion is analyzed. The experimental results are used to analyze the influence of the moving condition on the flow instability boundary. Finally, based on the experimental data, the empirical relation of the flow instability boundary is fitted.
