|settling velocity/settling rate;[分化]沉降速度;沉積速度
沉降速度(sedimentation velocity)是流體力學和環境科學中的重要概念,指懸浮顆粒在重力或離心力作用下,因密度差異在流體中定向移動的最終恒定速率。該現象遵循斯托克斯定律(Stokes' law),其公式可表示為:
$$
v = frac{2r(rho_p - rho_f)g}{9eta}
$$
其中,$v$為沉降速度,$r$為顆粒半徑,$rho_p$和$rho_f$分别為顆粒與流體的密度,$g$為重力加速度,$eta$為流體黏度。
Sedimentation velocity(沉降速度)指顆粒在流體(如液體或氣體)中因重力或離心力作用而向下運動的穩定速率。該術語常見于化學、環境科學和材料工程領域,具體解析如下:
物理定義
當顆粒密度大于流體時,受重力或離心力作用産生沉降。其最終達到的勻速運動狀态對應的速度即沉降速度,計算公式通常涉及斯托克斯定律(Stokes' law):
$$
v = frac{2r(rho_p - rho_f)g}{9eta}
$$
其中,( r )為顆粒半徑,( rho_p )和( rho_f )分别為顆粒與流體密度,( g )為重力加速度,( eta )為流體黏度。
