STUDY OF THE TEMPERATURE DISTRIBUTION IN A PARABOLIC CYLINDRICAL CONCENTRATORUSING A NANOFLUID AS HEAT TRANSFER FLUID

We have numerically studied the heat transfers in a Cylindrical-parabolic concentrator using nanofluid as transfer fluid for its use Solar Thermodynamics. After an analysis of work relating to solar concentrators and nanofluids, we have, after having described our physical system posed working hypotheses, written equations which govern collector. The latter well associated boundary conditions were then dimensionless order generalize problem reveal parameters that control operation absorber. To solve equations, used method finite differences algebraic obtained is solved thanks Thomas combined with iterative process line-by-line relaxation type. computer code developed made it possible find temperature distributions according spatial coordinates at different times. effects influences wind effect, axial transverse thermal dispersion, absorber length, geometric shape factor on average coolant analyzed. At end study, able identify most important give optimum
