In this work. Nusselt number and friction factor in the tube side of car radiator which is a type of fin and tube heat exchanger are experimentally determined. Two types of nanofluids including water-Al2O3 and water-CuO are used and experimental results are performed for three nanoparticles volumetric concentration (PVC) and for Reynolds number in the range of 3000-15000. The results ... https://tonerparts.shop/product-category/developers-and-photoconductor-units-pack/
