Optimization of energy saving devices ESD







FLOWTECH has performed a large number of pilot projects over the years that involved Energy Saving Devices (ESD). With the Naval Architecture background, the knowledge of hydrodynamics and CFD methods accumulated over the years our staff can perform the tasks efficiently and with high degree of confidence.

The ESDs require a very detailed analysis and accurate tools. With SHIPFLOW the simulations are performed in self-propelled conditions at model or full scale, see Energy Saving Device Evaluation in Full Scale Using Computational Fluid Dynamics, Broberg, L., Orych, M.. 2013. and An Efficient Numerical Technique To Simulate The Propeller Hull Interaction, Broberg, L., Orych, M.. 2012.
