A mathematical simulation to the cooling process
of a flat moving surface using a weak concentration
micropolar-nanofluid as a cooling medium has been investigated.
The modelling based on the conservation equations
of the unsteady case for the momentum and thermal
boundary layer taking into consider the effect of suction
process and thermal radiation. Using similarity transformation
technique, the conservation equations have been transformed
to ordinary differential equations that are solved
numerically for general case and analytically for the steady
case. Surface shear stress, couple shear stress, and the rate
of heat transfer are deduced, and the impact of these physical
characteristics on the final quality and the mechanical
properties of the surface to be cooled discussed. |
