Heat transfer augmentation of mixture ratio tio2 to sio2 in hybrid nanofluid

The efficiency in heat transfer fluid for cooling systems can be improved with the use of hybrid nanofluid. The combination of two or more single nanoparticles in the hybrid nanofluid improve their thermo-physical properties, hence contribute in heat transfer performance. The experimental investiga...
