Abstract
The influence of weak undulations on the turbulent flow in an axisymmetric pipe is studied through experimental investigations and numerical modelling using the eddy viscosity concept. Cross-section variations, wall curvature effects and the occurrence of reverse flow produce drastic changes in the flow structure. The calculation model has been extended to the numerical prediction of heat convection. Results obtained on the distribution of local heat transfer coefficients and on overall properties confirm that the Reynolds analogy is no longer valid in such a complex flow.
