Abstract:We study dynamical wormhole solutions in the framework of $f(T)$ f ( T ) theory of gravity with anisotropic fluid. We assume a general dynamical spherically symmetric wormhole spacetime with specific form of the shape function and scale factor. The scale factor is taken in the power-law form in order to meet the accelerated expansion of the universe. We discuss the behavior of energy conditions for three particular choices of equation of state, i.e., radial and transverse pressures in linear form with energy density and traceless fluid. The energy conditions satisfy for certain time intervals in all cases. The radial coordinate does not play any role in graphs and the validity or violation of energy conditions depend upon the time coordinate only. The graphical behavior of the energy conditions become equivalent for radial and transverse pressures in all the three cases.
