Abstract
Ethylene glycol has the characteristics of plasma and off course composed of ionized particles and it is also revealed by the literature that its rheological behavior is the best characterized by the power-law rheological model. Further, nanoparticles MoS2 and SiO2 are antioxidant, antifriction, and antiaging, therefore, their simultaneous suspension in ethylene glycol makes the mixture an efficient coolant for engines. Here, in this study, the objective is to investigate the thermal performance of liquid mixture (the mixture of ethylene glycol and nanoparticles, MoS2 and SiO2) theoretically. For this conservation laws and correlations among the thermophysical properties are simultaneously used for the modeling of heat transfer in ethylene glycol containing nanoparticles (MoS2 and SiO2). Models are transformed into their dimensionless form using the approach of symmetry analysis. The dimensionless models are solved numerically by the finite element method (FEM). Simulations are visualized and data is recorded in the form of graphs and numerical values. Comparative analysis has revealed that the thermal efficiency of ethylene glycol is much improved due to the simultaneous dispersion of MoS2 and SiO2. It is also found that ethylene glycol with a single type of nanoparticles (MoS2) is a less efficient coolant than the efficiency of ethylene glycol with hybrid nanoparticles.
