Using the Characteristic Of hybrid Mixture from Nanomaterials to Improve and Modified the Parameter of the Heat Transfer

Abstract

hybrid hybrid nanofluid is the fluid which have nanomateriales, this nanomaterials led to enhancement the heat transfer in the cooling equipement therefore the interest of the characteristic of the Nanomaterials to improve the properties of heat transfer of the fluid by using mixture of nanomaterials to obtain the best performance for the cooling. The nanomaterials which used in this work are zirconium (50-100 nm) oxide and titanium oxide (50-100 nm) with equal percent from each material. The percent which add to the fluid (water) is (0.2, 0.4, 0.6, 0.8, 1, and 1.2% wt. percent from the zirconium (50-100 nm) oxide and titanium oxide (50-100 nm). The result show that the factor of the friction of the fluid (water) decrease with increasing the Reynolds number, the factor of the friction of the hybrid hybrid nano fluid is decreasing with enhance the Reynolds number and the friction factor increase with increasing the percentage of the nanomaterials mixture. The overall heat transfer coefficient and Peclet number of the mixture of the hybrid hybrid nanofluid increases with increasing the weight fraction of the nano materials (zirconium oxide and titanium oxide). Nusselt number increases with increasing Reynolds and Peclet number and the content of the nanomaterials, however increase the weight content cause enhance in the viscosity of the hybrid hybrid nano fluid mixture led to enhance in the factor of the friction.
