The present work evaluates the performance of solar collector using
Al۲O۳-C۲H۶O۲-H۲O nanofluid as a working fluid through both experimental and CFD
-analysis. Ethylene-glycol water mixture (۴۰:۶۰ v/v) is used as base fluid, where α
Al۲O۳ nanoparticle of ۲۰ nm average size is dispersed for the preparation of
nanofluid of four different volumetric concentration (vol. conc.) of ۰.۰۵, ۰.۰۷۵, ۰.۱ and
۰.۱۲۵%. Three different volume flow rates of ۳۰ LPH, ۵۰ LPH and ۸۰ LPH are used.
CFD analysis is carried out through ANSYS FLUENT ۱۴.۵. From both experimental
and CFD analysis, an improvement in overall efficiency of solar collector is reported
when nanofluid is used as compared to water-ethylene glycol mixture. With ۰.۱۲۵%
vol. conc. of nanofluid Al۲O۳-C۲H۶O۲-H۲O (DI) maximum overall efficiency of about
۴.۶, ۷.۹ and ۱۴.۸% is reported at ۳۰ LPH, ۵۰ LPH and ۸۰ LPH, respectively from CFD
results while from experimental results maximum overall efficiency of about ۴.۳, ۷.۵
and ۱۳.۸% is seen at ۳۰ LPH, ۵۰ LPH and ۸۰ LPH, respectively. Also, with increasing
volume flow rate of working fluid, corresponding improvement in the overall
efficiency of solar collector takes place. Close agreement is also developed between
experimental and CFD result.
