Hydrodynamic Evaluation Request: Wave-Powered Cargo Vessel Using Internal Through-Channels

Hello everyone,

I am looking for qualified hydrodynamic feedback and critical evaluation regarding a new vessel architecture I have developed, published under an open CC BY 4.0 license.

The concept is a wave-powered cargo vessel where ocean waves pass through the hull in a series of internal channels. Inside these channels, a lift-force-optimized Archimedes screw (LFAS) extracts energy by hydrodynamic lift rather than classic mass-displacement.
The system also integrates:

DALAS (Dynamic Linear Adaptation System) for impulse extraction during wave slams

PHST (passive hydrostatic stabilization for maintaining microscopic air gaps)

A submerged, stable cargo module suspended beneath the surface unit

The aim is not propulsion by hull motion, but by extracting wave energy passing through the vessel.

I am not asking for validation of feasibility as a product — only for hydrodynamic review of the flow architecture, including:

Internal channel flow interaction

Lift-based screw efficiency in oscillating bidirectional flow

Pressure gradients and vortex formation

Stability effects of the submerged cargo module

Possible CFD approaches suitable for this geometry


The full technical description (including all subsystems) is available here:

I welcome critique, questions, and discussion from naval architects, CFD specialists and hydrodynamic engineers.

Thank you for your time and expertise.

There are a couple experts here in hydrodynamics. Make it easy for them to access your data. I can’t help you further; as no expertise.
