Influence of thermophysical properties on magnetite water-based ferrofluid heat transfer at sphere surface under magnetic field and thermal radiation

This theoretical study investigated the effect of thermophysical properties on Nusselt number when magnetic field and thermal radiation are exposed to ferrofluid flow at lower stagnation point a hot sphere surface. The thermo-physical important mechanisms considered in heat transfer process. Besides, ferroparticles volume fraction is one variables that can enhance exclusively studied conductivity diffusivity ferrofluid. Therefore, correlation between measured by Pearson product-moment coefficient method. strength association direction relationship these pertinent exhibited composed magnetite (Fe3O4) water (H2O). Regression analysis implemented predict number. results show positive as well diffusivity. Further-more, simple linear regression model proposed increasing resulted statistically significant given minuscule residuals value.
