【摘要】：肥皂泡體作為非線性流體,對(duì)于外界的作用有著極其復(fù)雜的非線性響應(yīng)。研究肥皂泡體中運(yùn)動(dòng)物體的動(dòng)力學(xué)行為能夠解釋和解決生產(chǎn)和生活中的很多相關(guān)問(wèn)題。通過(guò)理論建模、實(shí)驗(yàn)設(shè)計(jì)和數(shù)值模擬對(duì)于小而輕且與肥皂泡大小相差不大的球體在與肥皂泡體中的運(yùn)動(dòng)過(guò)程進(jìn)行研究。首先從統(tǒng)計(jì)力學(xué)的系綜角度給出了三維肥皂泡體動(dòng)力學(xué)行為的理論解釋,再?gòu)膶?shí)驗(yàn)上驗(yàn)證了在重力場(chǎng)作用下,小球在肥皂泡中的動(dòng)力學(xué)行為關(guān)系式,具有普遍性。
[Abstract]:As a nonlinear fluid, the soap bubble has extremely complex nonlinear response to the external action. Studying the dynamic behavior of moving objects in soap bubble can explain and solve many related problems in production and life. Through theoretical modeling, experimental design and numerical simulation, the movement process of small and light spheres with little difference with the size of soap bubbles was studied. In this paper, the theoretical explanation of dynamic behavior of three dimensional soap bubble is given from the angle of ensemble of statistical mechanics, and the equation of dynamic behavior of small ball in soap bubble under the action of gravity field is proved to be universal.
