Abstract
.Nanofluids are the next generation fluids that exhibit thermal properties superior to those of conventional fluids. Nanofluids play a vital role in various thermal applications such as automotive industries, heat exchangers, solar power generation, etc. Therefore, a generalized Brinkman-type fluid model has been developed to predict the heat transport properties of a flat-plate solar collector using a nanofluid in a rotating frame under the influence of transverse magnetic field B-0 and two cases are discussed. i) B-0 being fixed to the fluid (K = 0 ; ii) B-0 being fixed to the plate (K = 0). Thermal radiation and concentration are also taken into account. Furthermore, the classical model is converted to a generalized model using the Atangana-Baleanu (AB) fractional derivative and then the exact solutions are obtained via the Laplace transform method. A parametric study of all the governing parameters is carried out and some other important results are illustrated in tabular form. A comparison of several nano-sized solid particles, i.e. SWCNT, MWCNT, CuO, Al2O3 and TiO2 has been done in the current investigation and it is concluded that adding SWCNT in the working fluid (water) can augment the heat transfer rate up to 36.61%, which consequently upgrades the working ability of flat-plate solar collectors by enhancing their absorption power of solar radiation.
