In laminar pipe flow, radial heat transfer is limited to slow thermal conduction which results in a wide temperature distribution over the pipe cross-section. This is undesirable in many industrial processes as it leads to an uneven distribution of fluid heat treatment. Often the fluids involved are relatively viscous such as carboxymethyl cellulose and processing them under turbulent conditions i...
