Model of a ducted axial-flow hydrokinetic turbine – results of experimental and numerical examination

The article presents the numerical algorithm of the developed computer code which calculates performance characteristics of ducted axial-flow hydrokinetic turbines. The code makes use of the vortex lattice method (VLM), which has been developed and used in IMP PAN for years, to analyse the operation of various fluid-flow machines. To verify the developed software, a series of model tests have been performed in the cavitation tunnel being part of IMP PAN research equipment.
