## 5 Conclusions  
In this paper, Cu and Ag nanoparticles under the influence of magnetic field on unsteady Hiemenz flow and heat transport of incompressible nanofluid along a porous wedge sheet have been analyzed. Moreover, optimal homotopy asymptotic method (OHAM) has been used for obtaining the numerical solutions of two-dimensional radiative heat transfer. The influence of pure-water, Cu-water, and Ag-water particles in a magnetic field are investigated for velocity and temperature profiles in a porous wedge under the presence of solar energy. This research investigated the velocity \(h^{\prime}(\lambda)\) and temperature profiles \(\Theta(\lambda)\)against different parameters. The velocity and temperature profiles were also studied with the dynamics of nanofluids. Different parameters were applied to analyze their impacts on the nanofluid including a magnetic parameter \(M\), stretching rate \(m\), conductive radiation \(N\), unsteadiness \(\eta_{u}\), volume fraction \(\mu\), and heat source/sink \(\varepsilon\) parameters. The important outcomes of this research are presented as follows:  
* With the magnetic parameter \(M\), the temperature profile \(\Theta(\lambda)\) is observed to increase for pure-water, Cu-water, and Ag-water. Thus, an increase or decrease in \(M\) can cause an increase or decrease in the base fluid's temperature, respectively. The results indicated that copper and silver water heated fast with increase in \(M\). The boundary layer thickness of Cu-water, and Ag-water nanofluid is stronger than pure-water as M increases;
* With the conductive radiation parameter \(N\), the temperature profile \(\Theta(\lambda)\) is observed to increase in case of pure-water, Cu-water, and Ag-water. Thus, an increase or decrease in conductive radiation parameter \(N\) can cause an increase or decrease in the base fluid temperature. The results indicated that Cu and Ag water heated fast for \(N\), and they are closely aligned due to internal heat generation;
* With the increase in stretching rate \(m\) the temperature profile \(\Theta(\lambda)\) is observed to increase for the case of pure water, Cu-water, and Ag-water. Thus, an increase or decrease in the \(m\) can cause an increase or decrease in the base fluid's temperature. The graphs indicated that Ag-water heated fast for the increase in \(m\);
* Unsteadiness parameter \(\eta_{u}\), the temperature profile \(\Theta(\lambda)\) is observed to increase for the case of pure water, Cu-water, and Ag-water. Thus, an increase or decrease in \(\eta_{u}\) can cause an increase or decrease in the base fluid's temperature. Hence, mixing nanoparticles in nanofluid will have a considerable effect on liquid thermo-physical properties. The shows the increasing trend for pure water, Cu-water, and Ag-water;
* With the heat source parameter \(\varepsilon\), the temperature profile \(\Theta(\lambda)\) is observed to decrease for the case of pure water, Cu-water, and Ag-water. Thus, an increase in \(\varepsilon\) will cause a decrease in base fluid's temperature, hence affecting the base fluid inversely. This also indicates that the internal heat of the nanofluid is more pronounced than that of the base fluid;
* For pure water, Cu-water, and Ag-water, the impact of volume fraction of nanoparticles is observed. The temperature profile \(\Theta(\lambda)\) is seen to be decreased with constant magnetic field with the increase in volume fraction. Thus, an increase/decrease in \(\mu\) caused an increase/decrease in the nanofluid's temperature. This also confirms the notion that the thermal conductivity of the nanofluid is strongly dependent on the nanoparticle volume fraction;
* For the wedge angle \(\chi\), the temperature profile \(\Theta(\lambda)\) is observed to increase in case of pure-water, Cu-water, and Ag-water. Thus, an increase or decrease in angle of wedge \(\chi\) can cause an increase or decrease in the base fluid temperature.
