Researchon impact of nanofluids in heat pipes

Abstract

The basic aim of this study is to study the impact of nanofluids such as (Al2O3+Distilled water) in complete liquid form by dispensing aluminium oxide (fluid form) in base fluidand also to investigate the thermal performance of heat pipe solar collector using nanofluids under real operating conditions by theoretically and experimentally.The experimental setup is made with heat pipes and real time temperatures are measured for experimental efficiency. The theoretical investigation is to be done by using Computational Fluid Dynamics (CFD).The main innovation done in this experiment is the nanofluid prepared in complete fluid form without particles suspension to avoid the settling of nanoparticles in thermo syphon setup.For long term applications, we opted this method of preparing the fluid. The operating parameters to be considered are solar intensity, effect of tilt angle and effect of working fluid. Finally, the experimental output is to be compared with the theoretical one (CFD). The efficiency of theoretical was higher than experimental because ofassumptions considered in CFD. The nanofluid filled with 25% of total capacity of heat pipe i.e. 25ml/pipe.Heat pipes are best energy conserving technology for solar energy conversion.
