ABSTRACT
The paper presents the results of experimental research of orientation effect on heat transfer characteristics of a pulsating heat pipe (PHP). It is shown that transport of either mass or heat depends on PHP orientation against it`s axis. As a consequence of comparing experimental data with other authors’ results it was concluded that PHP thermal resistance depends not only on orientation but on some other determinal factors such as device construction and thermophysical properties of heat carrier.
