Numerical Simulation of Heat Transfer Enhancement in the Paths of Propulsion Systems with Single-Row Spherical and Oval Dimples on the Wall

Modeling the vortex intensification of turbulent heat transfer in narrow engine ducts using single-row dimples was carried out within framework multi-block computing technologies implemented a special VP2/3 package. The cases rectangular section with placement generators—single-row packages oval and spherical on initial hydrodynamic stabilized flow are excluded. connection between generated structures predominant increase compared to hydraulic losses for various dimple layouts has been established: zigzag, ladder, centers shifted longitudinal-transverse order. superiority removal from thickness inclined is shown—1.23 times ones decay resistance by 1.16 times.
