Abstract
The paper presents a technique for the numerical modeling of unsteady turbulent flows. A special feature of the technique consists of applying the immersed boundary method to ensure the fulfilment of the boundary conditions on the surface of the bodies in the flow for the resulting numerical solution. It is used for the numerical solution of the problem on a turbulent flow past a three-dimensional cylinder. The obtained numerical solution is compared with numerous experimental and calculated reference data and calculation results using boundary-fitted grids.
