| Summary: | Currently, there are different issues related to low thermal conductivity in the
conventional heat transfer fluid, such as water, ethylene glycol and oil, in engineering
electronic devices. Aiming to overcome this defect in conventional fluid, this research
focuses on nanofluid. Furthermore, dust is considered because in real world, impurities
exist and it may affect the flow. Therefore, this research studies the flow and heat
transfer characteristics of a dusty nanofluid over a moving plate in the presence of
magnetohydrodynamic (MHD). Three types of nanoparticles namely Copper Oxide
(CuO) , Aluminium Oxide 2 3 (Al O ) and Titanium Oxide 2 (TiO ) are considered. The
governing partial differential equations are converted into a system of non-linear
ordinary differential equations using a similarity transformation, then the non-linear
ordinary differential equations are solved using bvp4c program in MATLAB software.
The influence of non-dimensional governing parameters such as magnetic parameters
and nanoparticle volume fraction on the velocity and temperature profiles for fluid and
dust phases of dusty nanofluids are discussed. Then, the results obtained are analysed
by comparing two cases of boundary conditions, which are constant surface
temperature and convective boundary condition in terms of efficiency. The results
show that CuO has the lowest velocity but highest heat transfer rate on both fluid and
dust phase compared to 2 3 Al O and 2 TiO . Besides, the flow with prescribed surface
temperature has better heat transfer rate than the flow with convective boundary
condition |
