We evaluated a compact boardrider concept, essentially a shore‑breaker wave generator, to provide consistent ride quality at feasible energy input. Computational fluid dynamics was used to simulate pneumatic wave generation and wave shoaling over sculpted bathymetry, quantifying crest formation, runout and turbulence characteristics that affect rider experience and safety. Several surf‑wave geometries and actuation sequences were compared. A transient free‑surface model captured air and water interaction, with mesh refinement targeted at the breaking region, and verification and sensitivity checks on time step and dissipation controls underpinned the comparisons. Metrics included achievable wave height, repeatability, usable ride window, splash overs and loads on barriers. The recommended configuration produced predictable, rideable waves with a widened operating window and controlled splash while reducing energy per cycle relative to the baseline. The deliverables included clear visuals and time histories linked to performance indicators and practical guidance for nozzle layout, control envelopes and prototype test plans.
