Abstract
A turbine body includes a turbine rotor having a blade to rotate around an axis of rotation, and a housing including an inner wall surface surrounding the turbine rotor. During a rotation of the turbine rotor, a fluid is directed from a leading edge of the blade toward a trailing edge of the blade, and the blade is imparted with a first excitation force in response to the rotation of the turbine rotor. The inner wall surface has a plurality of grooves arranged along a circumferential direction that are positioned to intermittently face the trailing edge of the blade when the turbine rotor rotates, to generate a second excitation force that suppresses the first excitation force.
