Abstract The purpose of this study is to introduce a new analytical method namely, fractional
homotopy analysis transform method (FHATM) for series solution of the time fractional BBMBurger
equation. The homotopy analysis transform method is an innovative adjustment in Laplace
transform algorithm (LTA) for nonlinear fractional partial differential equation in fluid dynamics
and makes the calculation much simpler. The proposed scheme finds the solutions of nonlinear
problems without any discretization, restrictive assumptions and avoids the rounding off errors.
The numerical solutions obtained by the proposed method indicate that the approach is easy to
implement and computationally very attractive
