Title

CFD ANALYSIS AND EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER AND FLUID FLOW IN A PARABOLIC TROUGH SOLAR COLLECTORUSING TWISTED TAPE INSERTS AND HYBRID NANOFLUIDS

Abstract

This study was aimed to examine the effect of hybrid nanofluid on the thermal performance of Parabolic Trough Solar Collector (PTSC) was investigated. The simulation process was performed using Computational Fluid Dynamic (CFD).Nano technology plays very important role in the heat transfer solar applications, when used as a working fluid in parabolic collector enhances its efficiency due to its improved thermo-physical properties like thermal conductivity, heat capacity, density and viscosity. In order to achieve better heat transfer rate this can be done by changing the nature and properties of working fluids by introducing flow inserts is a common passive technique for enhancing the thermal performance of parabolic trough solar collectors. Nano fluids are a suspension of nano particles in a base fluid like water, ethylene glycol. In this paper both experimental and computational fluid dynamics study has been presented. Hybrid nanofluid possess enhanced thermal conductivity and better heat transfer coefficient as compared to the base fluid. Hybrid Nano fluid used is 0.5% (30% GO +70%TiO2) - H2O (DI). System performance is conducted under mass flow rate of 0.05kg/s. In ANSYS FLUENT 14.5 based computational fluid dynamics tool, the absorber tube is modeled as metallic stainless steel tube with working fluid flowing in it. Hybrid nanofluid is simulated using one-phase modeling techniques, while solar load cell and solar ray tracing are used for modelling the solar fluxes. Solar load model has been used for modeling solar fluxes. S2S radiation model has been used for modeling heat transfer comprising of conduction, convection and radiation. It has been reported from both experimental and CFD analysis that system performance is enhanced by using hybrid nano fluid as working fluid as compared with conventional fluid likes water. Also both experimental and CFD simulated data gives good result agreement.
