Investigation of temperature profile for nano fluid, pure water, ammonia and methanol in a heat pipe 


Abstract

The authors investigate thermal performance of pure water, nanofluid, ammonia and methanol on the heat pipe with 18 cm in length and 0.01m in diameter in this paper, approximately. The average difference between temperature profile of ethanol and methanol is about 36.4% in this case. The three polynomials with second order are defined in this study. The fluid passes through the heat pipe, experimentally. The curve fitting and regression of the experimental correlations show the accuracy of three curves are proper and so the predictions of temperature profile in the external zones are feasible.
