Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
At low vibration frequency (ω ≾ 200, the green shaded area of Fig. 1D), the measured Nu(ω) is essentially equivalent to the RB value of Nu(0). This is because when ω is small, the induced shear is too weak to effectively perturb the boundary layers and the system is still in a state of boundary-layer–controlled thermal turbulence.
