FORCED CONVECTION HEAT TRANSFER OF COBALT NANOFLUID IN A GLYCEROL–WATER BASE MIXTURE

Heat-transmitting equipment is subject to growing operating temperatures and heat transfer rates, which leads to the development of a nanofluid as an alternative. The forced convection heat transfer coefficient (h_n) and friction factor (f_n) of cobalt (Co) nanofluid in the glycerol–water (G/W) blends are reported in this work. A two-step procedure is used to produce a co-nanofluid of 0.18% maximum volume concentration in an optimal mix of 30% glycerol and 70% water, and an experimental setup is constructed. The test segment is a simple circular copper pipe operating under constant heat flux boundary conditions. The properties, concentration, and flow rate — all affect heat transfer in nanofluids; the h_n and f_n of the nanofluid were higher than those of the basic fluid. At a 0.18% volume fraction and similar Reynolds number, the maximum increase in h_n and f_n was 43.6% and 35.2%, respectively
