AB This paper studies unsteady convection heat and mass transfer of a fractional Oldroyd-B fluid in the presence of chemical
reaction and heat source/sink. Nonlinear coupled governing equations with time−space derivatives are derived and solved numerically. The effects of involved parameters on velocity, temperature, and concentration fields are analyzed. The results show that fractional derivative parameters have a remarkable influence on the viscoelastic properties of the fluid and play an opposite role in the boundary layer. With increase of the buoyancy ratio number, the velocity distributions rise, but the temperature distributions decline. Moreover, the heat source generates energy causing the temperature of the fluid to increase, while the heat sink absorbs energy which leads to the decrease of the temperature. Chemical reaction reduces the concentration boundary-layer thickness and improves the rate of mass transfer.
