Three-dimensional magnetohydrodynamic (MHD) numerical simulation is carried out to examine the influence of the Hall effect on MHD flow control in earth reentry flight with attack angles. In the simulation, the Hall effect is taken into account. Numerical results show that the Hall effect distorts the distribution of the electric currents around a reentry vehicle with attack angles. The distortion of electric currents leads to the generation of a side force on the vehicle, although the side force obtained under the present simulation conditions is considerably weak compared with a drag and a lift force. Furthermore, the numerical results indicate that the strength and the direction of the side force depend on attack angles, and also that the side force becomes zero at a particular attack angle.
