**5. Conclusions**

In the third chapter, we have presented the effect of double diffusion on the peristaltic flow of nanofluid through a curved channel. The governing equations for velocity, temperature, nanoparticles, and solutal concentration have been modified and illustrated under the suppositions of low Reynolds number and low wavelength. The solutions have been carried out by HPM. In the last section, graphical results have been sketched through figures. The major points of the study are given below:
