Open the CIPO recordAbstract From the Canadian patent
A computer simulation of bubbles enveloping a ship is performed by a. calculating a turbulent flow energy and an energy loss caused by an energy dissipation factor as well as an average fluid velocity in each of cells defined by three-dimensional orthogonal lattices constructed in a flow field including a turbulent boundary layer formed about a submerged surface of the ship; b. simulating a generation and ejection of a bubble into the turbulent flow layer at a given time from a given jet outlet with a given initial bubble velocity; c. calculating directional bubble velocities in each of cells according to the turbulent flow energy, the energy dissipation factor, the average fluid velocity …

Why it's free to use
- Filed September 17, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 17, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
