The search for the existence of Lyra manifold in a hybrid universe interacting with Van der Waals fluid using Bianchi type III metric is presented in this paper. To find the exact cosmological solutions, we use certain physical relations between the metric potentials and the average scale factor is assumed to be [Formula: see text] (see Ref. 1) describing the hybrid character of scale factor with the generation of a model of transitioning phase from early decelerating to the present accelerating universe. In this model, when we investigate further about the role of the Van der Waals fluid with Lyra geometry, interestingly, we found that this universe behaves as one containing with dark energy and at the late stage a part of the dark energy behaves as phantom type. This part being generated by the Lyra manifold itself may be taken as a source of dark energy. Some physical as well as geometrical aspects of the model universe are also presented.
