Heat Transfer Enhancement in Heat Pipe Using Nanofluid – A Review (original) (raw)
— For enhancement of heat transfer in heat pipe, Nano fluid found vital role and a new frontier in various engineering applications. This paper reviews and summarizes the work on heat pipes using nano fluids as a working medium. Various types of nano particle with different base fluids as proved its potential to improve thermal properties of working medium in heat pipe. The effect of filling ratio, volume fraction of nano practices on thermal performance in various kinds of heat pipe with different base fluids under various operating conditions has been discussed. Mechanism of enhancement of heat transfer after utilization of nano fluids in heat pipe has been explained. Also, influence of dimensionless on thermal resistance in terms of correlation has been studied. This paper discusses relativity of total heat resistance between the heat pipe with nano fluid and with existing fluids. Focusing towards the application this paper suggests the suitability of heat pipes in various heat generation problems.
