Xue and Maxwell numerical simulations for improved heat transmission in cylindrical film flow: A solar energy application

Abstract

Solar power plays a significant role in fulfilling industrial and household energy needs. A hypothetical analysis is accomplished to scrutinize the practical usage of solar power by enhancing the heat diffusion rate of the conventional liquid. Third-grade cylindrical film flow is considered in the existence of hydrodynamics (MHD), radiation, Ohmic heating, and Cattaneo–Christov heat flux. Water is a base liquid suspended with graphene oxide nanoparticles. An exact model is established and solved computationally by relating suitable comparisons. The considered flow model directly uses parabolic trough solar collector. A comparative analysis is performed on Xue and Maxwell nanomodels, and the results are explored with computational outcomes. It is found that the Xue nanomodel is actively enhancing the third-grade nanofluid temperature while the Maxwell nanomodel appreciates the heat transmission rate of the same.
