TL;DR: In this paper, a trapezoidal tank is used to increase the optical performance and alumina-water has been utilized as operating fluid to enhance the optical efficiency of nanomaterial flow.
Abstract: In current suggested design for domestic usage, arrangements of mirrors have been implemented as primary reflector Impose of trapezoidal tank intensifies the optical performance and alumina-water has been utilized as operating fluid which is practical due to kind of application For modeling, finite volume approach was imposed and extracted heat flux from solving the pure radiation were added as source term of turbulent modeling of nanomaterial flow Twisted tapes (TT) were installed within the pipe to augment the convective flow Inlet temperature (Tin), flow rate ( V • ), twist (TR) and width (WR) ratios are variables for various cases Irreversibility and thermal behavior were reported for all cases With existence of cavity, the optical efficiency enhances up to 735 % For lowest values of other parameter, augmenting TR and WR cause friction faction to increase about 2709 % and 922 % but increasing V • leads to decline of f about 2977 % With assumption of lowest values of other variables, augmentation of TR, V • and WR leads to intensification of Nu about 483 %, 1464 % and 169 % As Tin intensifies, η t h declines about 237 % when V • = 63, WR = 056, TR = 2With enhance of TR and WR, η t h goes up about 011 % and 0037 % with considering lowest values of other variables
