چکیده انگلیسی
All electrohydrodynamics (EHD) applications find their roots from the properties of the electrical double layer existing at the interface formed by the contact of a liquid with a solid material. The more is known about the properties of this electrical double layer, the more useful and practical applications can be found. This paper aims at contributing in the study of the response of the double layer's charge in a dielectric liquid to a step of temperature applied to the interface. The analyses are made considering different conditions were intrinsic properties such as ionic mobility and dielectric permittivity are assumed directly dependent of temperature variations or not. The weight of each of these parameters in the numerical model is assessed through parametric studies when each of them is assumed separately. The results show two major competing effects of the temperature step: a strong chemical reaction activity and a charge redistribution in the liquid volume. The predominance of each seems to depend on the temperature state (transient or stable) as well as the numerical conditions considered.
