Heat Transfer and Flow Characteristics of Coal Slurries under the Temperature Difference between Inside and Outside of the Channel

The pipeline transportation of coal slurries is always subject to a temperature difference between the outdoors environment and fluid body. As slurries’ viscosity typically dependent, flow accompanied by heat transfer. In this study, we used CFD method investigate distributions structures in straight curved channels, which has not previously been investigated, according our knowledge. First, results demonstrate that cooling process influences along stream. turns more sharply cooler channel, streamlines overlap at an earlier position within bend, velocity maximum zone wider. Cooling also significant impact on transverse flow. Because higher cooled thus difficulty shearing stream-wise direction, vorticity strength vortex are greater. central part channel points toward inner wall beginning resulting inner-wall biased distribution, as transfer partially carried out velocity. outer end outer-wall profile.
