The conservation equations in primitive variables are solved using the finite volume method and the SIMPLEC algorithm. The transient results are obtained for a Rayleigh number of 10<sup>6</sup> and five inclination angles (0°, 45°, 90°, 120° and 180°. The numerical model predicts flow instabilities for inclination angle of 0°, which avoids reaching the steady state. The steady state is reached after a long time for ϕ=180°.</p> ER -
