Abstract

Mathematical modeling of heat transfer and hydraulic resistance in pipes with turbulators is carried out on the basis of a proven model. The flow and heat transfer parameters were calculated by calculation based on multiblock computational technologies based on the solution of the factorized finite-volume method (FKOM) of the Reynolds equations (closed using the Menter shear stress transfer model) and the energy equation (on multi-scale intersecting structured grids) for turbulators with transverse section in the form of a square (s/h = 1) and in the form of an edge (s/h 1). The results of calculations showed the advantages and disadvantages of turbulators with a cross-section in the form of a square and in the form of an edge in relation to each other for various geometric and operating factors.
