Dr. Amir Faghri ABSTRACT Numerical and analytical simulation of heat pipes has progressed significantly in recent years. The state of the art has been advanced in steady state, continuum transient, and frozen start up simulation for high-, moderate-, and low-temperature heat pipes of conventional cylindrical and nonconventional geometries such as wing leading edges and spacecraft nosecaps. Part I of this review summarizes these advancements and discusses the important results for heat pipes with and without noncondensible gases. A considerable amount of theoretical and experimental development has been made related to two-phase closed thermosyphons as it is a simple but effective heat transfer device. Part II deals with the most recent advances in the simulation of thermosyphons. Part III provides recent analysis related to rotating heat pipe analysis. This type of motion significantly influences the heat transfer characteristics of heat pipes. Part IV presents analysis related to the prediction of axially grooved heat pipes. This includes heat transfer through thin films in the evaporator and condenser of the heat pipes with capillary grooves. The analysis details interfacial phenomena such as capillary and disjoining pressure as well as interfacial thermal resistance and surface roughness effects. As the size of heat pipes diminish, some performance characteristics are expected to be different from those of conventionally sized heat pipes. The last part of this review, Part V, covers the relatively new field of micro/miniature heat pipe technology. 217-290 pages |
