A bidirectional axial‐flow impulse turbine installed in an oscillating water column raises the question of damping at different wave conditions. This article reports unsteady performances of such a turbine in an airflow test rig. The rig has a piston‐cylinder arrangement, and the piston, when reciprocating, generates the oscillatory airflow.
