Abstract:
The heat and mass transfer features for the sake of copper – water nanofluid which flows together with viscous dissipation as well as combined effect of free and forced convection, and these are studied along the inclined plate in regard to the porous medium. The considered physical model in terms of governing partial differential equations is transformed to a dimensionless system as ordinary differential equations with the aid of using appropriate similarity transformations. The resulting system based on the transformed dimensionless equations is solved numerically by generating and executing FORTRAN code with the aid of applying modified Nachtsheim – Swigert shooting iteration technique with the Runge – Kutta integration procedure. For the accuracy of the numerical outcomes, comparisons are made for special cases with the existing published results in the literature and comparatively acceptable comparisons are reached.
Subsequently, the effects of different physical parameters as Eckert number, fluid suction, Schmidt number, nanoparticles volume fraction, permeability parameter together with other operational parameters are exposed graphically upon the flow of fields such as in terms of velocity, temperature along with concentration fields. The dependence of local skin friction coefficient, local Nusselt number together with Sherwood number are quantified and discussed in terms of graphical and the tabular form. As well, the obtained outcomes showed considerable effects on the heat and mass transfer. To enhance the Eckert number, it is observed that the wall shear stress, as well as, concentration difference of the field reduces, whereas the temperature difference of the flow field increases as a result that the skin friction coefficient in combination with local Sherwood number and local Nusselt number reduces for copper –water nanofluid.
In addition, the numerical solutions are carried out for the existence of concerning the magnetic field with heat and mass transfer characteristics on the same field of the considered nanofluid flow. The influence of significant parameters as magnetic parameter together with other relevantparameters are examined and calculated. It is expected that the skin friction coefficient is established to increase with increase of magnetic field strength. More than that, the effects of different significant parameters on the considered nanofluidflow field in presence of chemical reaction characteristicsare examined and analyzed thereafter. It is observed that the local Sherwood numberincreases because of the increase of chemical reaction.
However, the impacts of different types of nanofluids on the considered flow field are explored and observed that the local skin friction coefficient in conjunction with local Nusselt number and local Sherwood numberincrease due to copper – water nanofluid flow as comparing with the nanofluidslike as titanium dioxide – water and aluminum oxide – water. The works addressed in this thesis can be beneficial and helpful to the academic, experimentalist as well as simulation experts, and these works can be easily extended to develop the behavior of the nanofluid flow through complex circumstances.
