The soil was placed in batch reactors and nanofluid iron oxide was added to the soil for [Cd.sup.2+] removal.
Consider a steady, two-dimensional flow of an incompressible viscous nanofluid past a linearly semiinfinite stretching sheet.
The pressure drop obtained using the nanofluid for each channel show lower values with the addition of nano particles in place of solid or porous pin fins.

where [U.sub.i], P, and [bar.T] are the mean nanofluid velocity, pressure, and temperature, respectively, [u'.sub.i] is the fluctuation flow velocity, and [[bar.[epsilon]].sub.kl] is the mean rate-of-strain tensor.
This was because the thermal diffusivity of nanofluid depended on some parameters, such as nanoparticles material, concentration of particles, size, base fluid, and surfactant.
Temperature-dependent thermophysical properties for all utilized heat transfer fluids were determined so that, compared to water as a thermal fluid, the improvements in the heat transfer rate with nanofluid could be evaluated.
