Abstract: The dependence of the integral heat transfer distribution on the Prandtl number for turbulent convective heat exchange in a pipe with a sequence of periodic protrusions of semicircular geometry is investigated by a computational method based on the numerical solution of the system of Reynolds equations closed using the Menter shear stress transfer model and the energy equation on multi-scale intersecting structured grids.
