| Summary: | The Biefeld-Brown is a fascinating effect with which levitation can be reached without moving or rotating elements. Static voltage is applied between asymmetric electrodes and a force towards the small electrode is generated. This effect is studied experimentally in this paper. Using this effect a set of experiments is conducted trying to clarify the relation of the model geometry to the induced force. The results show clear relations of the generated force to the model structure and dimensions. As the asymmetry is stronger, the force is stronger. According to the experimental results, a set of preferred parameters is given to strength the effect. Choosing the geometrical properties properly led to improvement of factor ∼9 in the generated force and efficiency. Nevertheless, some results provides contradictions to earlier models of electrohydrodynamicmic (EHD) describing the effect and reveal unresolved questions regarding this effect. |
