Hybrid nanofluid Consist of mixed more than one nanopartical with working fluid such as CuO A1203, TiO2 with water and the Thermo physical properties of hybrid nanofluid depend on the type of nanoparticle. For example hybrid nanofluid consist of two of nanofluid Thermo physical properties of hybrid nanofluid Hybrid Nanofluid Phnf = Pfl = p;(1-42) [(1-4) + 4 (B;})] (PCp)nag = (PCp), (1—4₂) [(1–4₂) + 4, Hj Mined (1-01)25(1-02) 25 Ps +$2ps2 Kinf köf = (pcp)st (pcp)f ksz + (S-1)kbf-(S-1) ₂ (kbf-ksz) k2 +(S-1)ky + d₂ (kb-ksz) +$₂ (PCp) sz Where kbf_ks1 + (S-1)kg-(S-1) 1 (ky-ks1) ksi + (S−1)kƒ + ₁ (kj-ks1) = kf Example: evaluate the thermal conductivity of hybrid nanofluid consist of Cu, TiO2 ,H20, 9₁-0.02 for Cu, 9₁-0.03 for TiO₂ Density, specific heat and thermal conductivity of base fluids and nanoparticles H₂O Cu Properties/constituents 997.1 8933 Density, p (kg/m³) 4179 385 Specific heat, Cp (/kg K) Thermal conductivity, k (W/mK) 0.613 401 TiO₂ 4250 686.2 8.9538
