Numerical model application in rowing simulator design

simulator. Nowadays there are two main approaches in the simulator design. The first one includes
a static water with no artificial movement and counts on specially cut oars to provide the same
resistance in the water. The second approach, on the other hand uses pumps or similar devices to
force the water to circulate but both of the designs share many problems. Such problems are
affecting already built facilities and can be summarized as unrealistic feeling, unwanted turbulent
flow and bad velocity profile. Therefore, the goal was to design a new rowing simulator that would
provide nature-like conditions for the racers and provide an unmatched experience. In order to
accomplish this challenge, it was decided to use in-depth numerical modeling to solve the hydraulic
problems. The general measures for the design were taken in accordance with space availability of
the simulator´s housing. The entire research was coordinated with other stages of the onstruction using BIM. The detailed geometry was designed using a numerical model in Ansys Fluent and parametric auto-optimization tools which led to minimum negative hydraulic phenomena and decreased investment and operational costs due to the decreased hydraulic losses in the system.
