SUMMARY: In this work I aim to improve our understanding about the interplay between feeding and feedback, and its effect on the morphology of the central gas reservoirs surrounding the SMBH, using purpose-made small-to-medium scale simulations. To do this I had to fulfil the following tasks: Investigate how gas morphology in the central few parsecs depends on the properties of the infalling material by creating an idealised model of the CNR region. Develop a more realistic prescription for tracking SMBH accretion in hydrodynamical simulations and determine how corrected timing and extent of activity affect the surrounding dense material. Develop a computationally efficient method for AGN feedback injection. Investigate the AGN outflow expansion into a cool and clumpy ISM and how this added complexity affects the coupling efficiency between the AGN wind and the ISM.
