INTRODUCTION
Over the past few years, there has been rapid development of practical engineering solutions to a multitude of heating problems. Heat generated in micro--devices used in manufacturing and electronics require special solutions. Closed-looped oscillating heat-pipe with check valves (CLOHP/CV) in Fig. 1. is a very effective heat transfer device. Heat is transported from the evaporator to the condenser by the oscillation of the working fluid moving in an axial direction inside the tube. In this type of system the inner diameter of the pipe is important. It must be small enough so that under operation conditions liquid slugs and vapor plugs can be formed. ...
