Background:
In this paper, transient two-dimensional laminar boundary layer viscous incompressible free
convective flow of water based nanofluid with carbon nanotubes (CNTs) past a moving vertical cylinder with variable
surface temperature is studied numerically in the presence of thermal radiation and heat generation.
Methods:
The prevailing partial differential equations which model the flow with initial and boundary conditions are solved
by implicit finite difference method of Crank Nicolson type which is unconditionally stable and convergent.
Results:
Influence of Grashof number (Gr), nanoparticle volume fraction ( ), heat generation parameter (Q), temperature
exponent (m), radiation parameter (N) and time (t) on velocity and temperature profiles are sketched graphically and
elaborated comprehensively.
Conclusion:
Analysis of Nusselt number and Skin friction coefficient are also discussed numerically for both single wall
carbon nanotubes (SWCNTs) and multi wall carbon nanotubes (MWCNTs).
