| Summary: | The problem of double stratification on boundary layer flow and heat transfer
induced due to a nanofluid over a vertical plate in the presence of chemical reaction
is investigated. Nanoparticles have a great potential to improve the thermal transport
properties compared to conventional particles fluids suspensions, mili meter and
micro meter sized particles. The transport equation which employed in the analysis
including the effect of Brownian motion, thermophoresis parameter, buoyancy ratio
parameter, thermal stratification parameter, solutal stratification parameter and
chemical reaction rate parameter. The non-linear governing equations and their
associated boundary conditions are initially cast into dimensionless forms by
similarity variables. The resulting systems of equations are then solved numerically
by using very robust computer algebra software MAPLE 18. This software uses a
fourth-fifth order Runge Kutta Fehlberg method as a default to solve boundary
values problems numerically using the dsolve command. Numerical results are
obtained for dimensionless velocity, temperature and concentration distribution of
particles. It is examined that the dimensionless velocity of the fluid decreases with
the increases of thermal and solutal stratification parameter. The numerical results
are compared and found to be in good agreement with the previous published result
on special cases of the problem. |
