PINN Ocean Flowsettings for PINNThis note introduces Ninja, PyTorch’s MPS backend, and NVIDIA DALI as tools relevant to setting up a PINN workflow. It outlines their roles and the hardware constraints to…2025-08-04Fluid Mechanics
Kelvin WedgeSurface Waves Generated by A Travelling Pressure PointWe study the free-surface response to a moving pressure point over finite depth using 2D Fourier transforms, contour deformation, and a radiation condition. By analysing poles…2025-05-05Fluid Mechanics
Kelvin WedgeRay Geometry, and Wave Action in Uniform CurrentsWe summarize the ray-theoretic description of Kelvin ship waves in deep and finite depth, deriving the relationship between wavevector and wake angle, the Kelvin wedge, and the…2025-05-03Fluid Mechanics
Kelvin WedgePhase Geometry of Ship Waves: Deriving $p=a \cos ^2 \theta$We derive the ship-wave crest relation \(p=a \cos ^2 \theta\) in deep water from the Doppler-shifted dispersion relation and stationary-phase arguments, interpret \(a\) as an inte…2025-04-17Fluid Mechanics
