Experimental study on properties of hybrid stable & surfactant-free nanofluids GNPs/CNCs (Graphene nanoplatelets/cellulose nanocrystal) in water/ethylene glycol mixture for heat transfer application

The heat transfer capacity of any thermal cooling system depends on two factors, i.e., the selection coolant and geometrical pattern approach. This article summarizes nanofluids' preparation ranging from 0.01 % to 0.2 using Graphene nanoplatelets & CNC dispersed in a base fluid. combination water with ethylene glycol (EG) is form customary transmit liquids regularly utilized numerous energy practices maintain water's decent (or heating) capability; thus, 60:40 ratio EG: W mixture used as fluid for thermo-physical properties enhancements. These nanofluids prepared are not surfactants it results generating bubbles contaminating channels, influencing overall performance. XRD FESEM techniques were analyze surface. investigated remained stable, no substantial sedimentation 30 days. GNPs/CNC at 0.1% volume concentration has proper stability showing excellent colloidal 60:40. present hybrid nanofluid ability switch traditional fluids leading efficient compact structures.
