A numerical analysis is conducted to investigate the effect of periodic variation of acceleration upon the natural convection of fluid in a closed cavity with heated end walls. Acceleration or g-jitter is applied with inclination against the temperature gradient direction. Even if the acceleration is periodic, a net circulation remains by integrating the velocity and temperature distribution over one period. With the increase of the frequency, the direction of convection is inversed, because, the phase shift of horizontal velocity and temperature fields against the g-jitter becomes prominent. The numerical results are examined in comparison with simplified analytical solutions.
