This experimental study investigates the thermal properties and conductivity of a hybrid nanofluid composed of 89 % SiO2 and 11 % MWCNT in a mixture of 45 % ethylene glycol and 55 % water . The nanofluid was prepared using a two - step method, and its thermal conductivity was measured across various volume fractions ( ranging from 0.1 % to 1.45 % ) and temperatures ( from 26.7°C to 50°C ) using a KD2 Pro device . The results indicated a 25.1 % increase at a volume fraction of 1.45 % and a temperature of 50° C . By employing the response surface method, a 5th -degree polynomial equation accurately describes the complex interaction between temperature and volume fraction (R2 = 0.9996) . The model's high accuracy is demonstrated by a Response surface method margin of deviation ranging from 0 . 238 % to 0 . 355 % .
