A set of hydrodynamic parameters, which play a major role in cleaning of closed process systems, have been identified. Besides the wall shear stress, another significant factor is the nature of the recirculation zones present. Steady recirculation zones can reduce cleaning efficiency. For milk protei...
The τ-value formula Tao值的公式 τw = shear stress at the wall, N/m² (Pa) 壁面剪切力 f ⋅ ρ ⋅ V 2 ∆P ⋅ Dh τw = = 2 2⋅ L –Higher pressure drop ⇒ Higher shear stress 高压力降⇒高剪切力 f = friction factor, -摩擦因数 V = flow velocity 流速 L = ...
