Roll CoolingHeat Transfer and Fluid Flow Laboratory

For roll cooling investigation the surface temperature or heat transfer coefficient at the roll needs to be determined. When roll works in the industry to get its surface temperatures or temperatures under the surface is usually impossible. The rotational aspect of the cooled object makes the problem even more complicated.
