Submarine hydrodynamics for off-design conditions
Journal of Ocean Engineering and Marine Energy, 2022 AbstractTraditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of the boat, attention is also paid to operating near or at the surface and fortunately, computational tools and experimental ...

Improved Body Force Model for Estimating Off-Design Axial Compressor Performance
Energies, 2022 Based on the COMSOL software, body forces substituted into the Reynolds-averaged Navier–Stokes (RANS) equations as the source terms instead of the actual blade rows were improved to better predict the compressor performance. Improvements in parallel body
