Abstract
Most internal combustion engines are fluid cooled using liquid coolants mostly water and ethylene glycol, whose heat
transfer capabilities are limited. An alternative for improving their thermophysical properties is the addition of metal
oxides so as to make Nanofluids. This study investigates car antifreeze and coolants by comparing water-based and
ethylene glycol based Nanofluids to determine the Nanofluid which provides optimum cooling. The governing
equations are non–dimensionalised using similarity transformation and the resulting equations solved numerically
using the Runge–Kutta fourth order scheme. Graphical results of pertinent parameters on fluid velocity, temperature,
skin friction and rate of heat transfer are presented and discussed in depth putting into consideration the industrial
application. It was observed that the magnetic field slows the fluid flow while increasing the fluid temperature. Also
ethylene glycol Nanofluid offers better cooling capabilities.
