An Experimental Study on Charge Injection to Non-Conducting Liquid for Electrohydrodynamic Atomization

Abstract In an isothermal liquid, only the Coulomb force which is the force acting on the free charges, can contribute to permanent electrohydrodynamic motion. In the absence of a direct charge injection, pumping can be achieved due to the charges associated with the heterocharge layers of finite thickness in the vicinity of the electrodes which are based on the process of dissociation of a neutral electrolytic species and recombination of the generated ions. This type of pumping is referred to as pure conduction pumping. The conduction pumping mechanism is experimentally investigated here with three different electrode designs. Sufficient pressure heads are generated with very low electric power requirements making the EHD conduction pumping attractive to certain applications such as capillary pumped loops and heat pipes.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
