Analytical Study of Temperature Distribution of the Electroosmotic Flow in Slit Microchannels

چکیده
Abstract: Presence of externally applied electric field can cause the flow field in the micron and submicron channels; this generated flow field is called electroosmotic. In this type of flow field, the presence of the external electric field causes the extra generated heat in the domain that may affect the performance of the system (Joule heating effect). In the present study, an analytical approach has been proposed to find the temperature distribution of the electroosmotic flow field in the slit microchannels. Using the obtained method, the effects of microchannel height and external electric field on the temperature distribution of the flow field have been examined. It is revealed that, for the larger microchannels, the effect of the external electric field can be intensified on the temperature of the flow field. However, in the small microchannels, its effect may be negligible.
