Heat Transfer in a Laminar Flow of a Non-Newtonian Fluid in a Helical Pipe
Liping Cheng and Andrey V. Kuznetsov
A numerical investigation of heat transfer in a fully-developed laminar flow of a non-Newtonian fluid in a helical pipe is carried out. The momentum and energy equations are derived in an orthogonal helical coordinate system. The case of a constant wall heat flux is considered. The effects of the Dean number, Germano number, and Prandtl number with a fixed Reynolds number on the hydrodynamics and heat transfer in non-Newtonian fluid flow in helical pipes are investigated.
