Analysis of Solar Heat Pipe by Optimizing Volumetric Fluid Fill using Fluent

Abstract

Drying of products obtained from plants is an important step in converting seed and other products into usable forms. Currently conventional methods such as drying using woods are in vogue. This paper aims to investigate the use of solar energy for drying cardamom in place of conventional drying methods. The solar heat pipe, a main component of the dryer is designed and analysed for its performance using computational fluid dynamics (CFD). Based on the performance so obtained, simulations were carried out to improve the thermal efficiency and optimize the volumetrically fluid fill in the solar heat pipe. The results of the study indicate that solar heat pipe can effectively be used for drying and will result in saving of firewood and oil. Also it can save environment from pollution and greenhouse gases.

Experimental Investigation of Heat Pipe Heat Exchanger with Hybrid Nanofluids

“…Based upon these classifications hybrid Nanofluids was prepared. When some amount of nano-Al 2 O 3 was added and the thermal conductivity of microcapsules increased in an experiment to find out characterization and thermal properties of paraffin microcapsules modified with nano-Al 2 O 3 , and the melting and crystallization enthalpy was 93.41 J/g and 92.43 J/g, respectively this shows that nano-Al 2 O 3 will increase the heat transfer [2]. Tio 2 has melting point of 1800°C and good thermal conductivity.…”
