Riassunto analitico
In the last decade, the continuous development of electronics components has pointed out the need for a change in mind with regard to thermal management. In the present scenario, Pulsating Heat Pipes (PHPs) are novel promising two-phase passive heat transfer devices that seem to meet all present and possibly future thermal requirements.<br>Although grouped as a sub-class of heat pipes, the PHPs governing phenomena are quite unique and not completely understood. In particular, single closed loop PHPs that might be considered as the basic constituents of multi turns PHPs manifest a large number of drawbacks mostly related to the device thermal performance and reliability, i.e. the occurrence of multiple quasi-steady states during operation.<br>Many attempts have been made in literature in order to face on the problem and promote the circulation of the working fluid in a preferential direction. The present research work proposes the application of an electric field as a candidate technique.<br>
