Outline of Final Research Achievements |
In this study, a numerical simulation method for predicting complex turbulent heat transfer fields was developed based on a LES (Large Eddy Simulation) method. Contrary to my initial expectations, the development of a velocity reconstruction method, which is based on vortex elements near the domain interfaces, was not accomplished perfectly. Instead, a multi-block LES method was newly developed based on three-dimensional interpolation techniques. By applying this method, a new concept of turbulent flow simulation, “concurrent simulation” was proposed and developed. The concurrent simulation technique was applied to investigate the effect of a slight change in the shape of turbulence promoters on the resultant turbulent heat transfer fields downstream the turbulators under the completely same fluctuating inflow fields for each turbulator.
