| Outline of Final Research Achievements |
To clarify the mechanism of the electromagnetic force generation on the magnetohydrodynamic braking in rarefied atmospheres, we conducted an arc wind tunnel experiment and its numerical simulation. Our previous analytical study has predicted that an insulating boundary in a flow is necessary to activate magnetohydrodynamic braking in a rarefied flow. To validate this analytical prediction, we investigated the dependency of the total drag on the insulating boundary location by varying the arc plume boundary location. As a result, the measured and computed total drags increase by applying the magnetic field. The computation is consistent with the analytical prediction because the total drag increases by moving the insulating boundary to the test model. However, the measured electromagnetic drag increase is insensitive to the insulating boundary location because the flow is denser than expected.
