development of new model to predict dynamic viscosity of ethylene glycol based nanofluid containing mg(oh)2

in this study, the dynamic viscosity of mg(oh)2-ethylene glycol(eg) is measured. also, new model for determining the dynamic viscosity of the nanofluid is proposed. due to the limitation of the previous correlations in order to predict the dynamic viscosity of the mentioned nanofluid, a new practical equation is suggested base on the experimental correlations. the results indicate that while the solid volume fraction is increased, the dynamic viscosity is increased simultaneously. it can be interesting to note that at lower temperatures this increase is more noticeable than those in higher temperatures. in addition, it is shown that a special temperature of 55⁰c, the solid volume fraction has no significant impact on the dynamic viscosity of the nanofluid. this unique consequence can be considered as a paramount breakthrough in the engineering and industrial applications.
