AB - <p style="text-align: justify;">The present study is concerned with unsteady natural convective boundary
layer flow and heat transfer of fractional second-grade nanofluids for different
particle shapes. Nonlinear boundary layer governing equations are formulated
with time fractional derivatives in the momentum equation. The governing
boundary layer equations of continuity, momentum and energy are reduced
by dimensionless variable. Numerical solutions of the momentum and energy equations are obtained by the finite difference method combined with L1-algorithm. The quantities of physical interest are graphically presented and
discussed in details. It is found that particle shape, fractional derivative parameter and the Grashof number have profound influences on the the flow and
heat transfer.</p>
