A Comparison between Classical DES and DDES Using the In-house Computational Code
Original language description
The comprehensive three-dimensional turbulent flow study was performed using the in-house computational code. The simulation of the turbulent effect on the incompressible flows was carried out by the turbulent hybrid model. In general, turbulent flow simulation belongs to the time consuming calculations and requires mostly finer grid resolutions at boundaries. To find appropriate computational conditions, the numerical methods, code compilation and code calculations were investigated. Using optimal compilation options and grid construction, the computational performance can be increased and therefore, higher grid resolutions can be achieved and total required computational time can be reduced. Furthermore, the aspect of the two turbulent flow approaches represented by Delayed-Detached Eddy Simulation (DDES) and classical Detached Eddy Simulation was studied on the benchmarks of the turbulent flow past a cylinder at Reynolds number 3.900.
