HydroComp PropElements 2021 Update
New Features for Improved Wake-Adapted Propeller Design and Analysis
Development in 2021 for HydroComp PropElements offers new features across the range of applications.
PropElements + FINE/Marine Coupling
User testing is underway for the new coupling of HydroComp PropElements with NUMECA’s FINE/Marine CFD software. One of the challenges of full self-propulsion analysis with CFD is the computational load required to model the propeller within the 3D space. When coupled with FINE/Marine as a higher-order actuator disk replacement, PropElements calculates velocity fields and propeller body forces for the wake field, offering a significantly improved model of propeller performance for self-propulsion simulation at a fraction of the computational cost of full “sliding grid” 3D analysis.
Updates to the Prediction of Nozzle Contribution
A number of updates have been added to the modeling of nozzle contribution for the design and analysis of ducted propellers in PropElements. New for 2021 include:
- Updated model for 19A and High Efficiency nozzles.
- New scale correction for nozzles to better predict large nozzle.
- Addition of nozzle style 30 as a minimum-drag non-contributing nozzle, and style 38 for symmetric fore-aft performance.
- Indicator for potential inception of critical cavitation.
