| description | Homogeneous and heterogeneous chemical reactions in partially ionized magnetonanofluid are investigated theoretically using finite element method. The effects of ions and electrons collisions on the transport of heat and mass are analyzed for both the cases of heterogeneous and homogeneous chemical reactions. The simultaneous effects of dispersion of nano-sized particles in partially ionized nanofluid in the presence of magnetic field are also investigated. Through numerical experiments, it is noted that the temperature of partially ionized nanofluid increases as the electrons collision rate is increased, whereas a reverse trend is noted when ion collisions are increased. The transport rate of reacting species decreases when heterogeneous and homogeneous chemical reactions strengths are increased. It is also observed that the effect of electron collisions on the flow in
y
-direction is opposite to that of ion collisions on the flow in
y
-direction. Homogeneous and heterogeneous chemical reactions have similar effects on concentration of chemically reacting species in qualitative sense. However, in quantitative sense, homogeneous chemical reaction has more significant effects on concentration as compared to the effect of heterogeneous chemical reaction. |
