Objective To investigate the radial distribution of temperature for the oscillatory flow in artery, and its relationship with other mechanical quantities. Methods Considering oscillatory flow as the first-order terms, the equations of motion on the basis of Boussinesq's approximation can be treated by perturbation theory. Results The equations of oscillatory flow including temperature are derived, and the radial distributions of temperature, pressure and velocities for the oscillatory flow in artery are obtained. Conclusion (1)The distributions of temperature and velocities are closely related to oscillatory frequency, the amplitude of the temperature fluctuation is inverse proportional to oscillatory frequency.(2) With the increasing of the oscillatory frequency, the gradient of temperature and velocities is mainly restricted in the near-wall layers. (3) The distributions of temperature and axial velocity are comparable.
