MAGNETOHYDRODINAMIC DUSTY HYBRID NANOFLUID PERISTALTIC FLOW IN CURVED CHANNELS

This paper presents numerical simulations for a MHD convective process in curved channels. The worked suspension consists of water as a based hybrid nanofluid and two types of the nano-particles, namely, Cu and Al2O3. Two systems of the governing equations are formulated for the hybrid nanofluid and dusty phases. The hybrid nanofluid system is modeled in view of lubrication approach. The governing equations are mapped to a regular computational domain then they solved numerically using the fourth order Runge-Kutta method. The obtained findings revealed that the growing in the Hartmann number causes a reduction in both of the hybrid nanofluid and dusty velocities while the mixture temperature is enhanced. Also, the temperature distributions are supported when either the Grashof number or the amplitude ratio is altered.

Automated summary

This study presents numerical simulations for an MHD convective process in curved channels using water-based hybrid nanofluid and Cu, Al2O3 nanoparticles as the suspension. The results show that an increase in the Hartmann number leads to a decrease in the velocities of the hybrid nanofluid and dusty phases, as well as an increase in the mixture temperature, with temperature distributions affected by changes in the Grashof number and amplitude ratio.
