Sažetak
This paper presents numerical simulations with dominant free surface effects. Wave loads exerted on static offshore structures are calculated. Simulations are carried out using Finite Volume Method (FVM). Mathematical model of two phase incompressible flow is based on Naiver-Stokes equa- tions. Volume of Fluid (VOF) [4] method is used for interface capturing. Waves are generated using relaxation zones principle [3]. Pressure-velocity coupling is obtained by PIMPLE algorithm, a combination of SIMPLE and PISO algorithm. It allows calcula- tions with higher Courant numbers, reducing required computational time. Simulations are calculated with OpenFOAM software package. The method is validated with two test cases. In first simulation truncated vertical cylin- der immersed in water is exposed to incoming waves. Forces on cylindrical column are calculated. Five cases of harmonic waves with different frequencies and wave heights are investigated. Data is compared with experimental results from [2]. The forces on the column in the direction of wave propagation show good agreement with experimen- tally measured forces. The second case describes freak wave initialization and simulation. Finally it is concluded that CFD simulations for given cases give acceptably accurate results.
