ABSTRACT = {In this paper, numerical investigations for peristaltic motion of dusty
nanofluids in a curved channel are performed. Two systems of partial differential
equations are presented for the nanofluid and dusty phases and then the approximations of the long wave length and low Reynolds number are applied. The physical domain is transformed to a rectangular computational model using suitable
grid transformations. The resulting systems are solved numerically using shooting
method and mathematical forms for the pressure distributions are introduced. The
controlling parameters in this study are the thermal buoyancy parameter <i>Gr</i>, the
concentration buoyancy parameter <i>Gc</i>, the amplitude ratio ϵ, the Eckert number
<i>Ec</i>, the thermophoresis parameter <i>N<sub>t</sub></i> and the Brownian motion parameter <i>N<sub>b</sub><i>
and the dusty parameters <i>D<sub>s</sub></i>, <i>α<sub>s</sub></i>. The obtained results revealed that an increase
in the Eckert number enhances the temperature of the fluid and dusty particles
while the nanoparticle volume fraction is reduced. Also, both of the temperature
and nanoparticles volume fraction are supported by the growing of the Brownian
motion parameter.},
