In order to prevent the environmental pollution, the dryers are commonly used to treat sludge that one of sewages is polluting the quality of water. Generally, the drying method is various as to the property of material and use. Rotary dryer is a good apparatus to treat them. The rotary dryer is the way that is to make substance transmission and heating using hot air between sludge particles and heated gas. In this paper, we performed a numerical analysis of the inner air flow of the ANDRICH type dryer through the changing rotational speed from 3rpm to 10rpm. A PIV can be applied to research a inner flow of ANDRICH type dryer.

Generally, the drying method is various as to the property of material and use. Rotary dryer is a good apparatus to treat them. The rotary dryer is the way that is to make substance transmission and heat using hot air between sludge particle and heated gas. In this paper, we performed a numerical analysis for the inner air flow of the 3-pass rotary dryer through the changing rotational speed from 3rpm to 10rpm. In this result, we found that 3rpm is effective to dry material in terms of heat transfer because velocity fluctuation of a large scale is occurred inside the first drum and second drum. Also we confirmed that 5rpm and 8rpm showed up uniform flow at the center area of the first drum.
