In this paper we present a mathematical model and a numerical workflow forthe simulation of a thermal single-phase flow with reactive transport in porousmedia, in the presence of fractures. The latter are thin regions which mightbehave as high or low permeability channels depending on their physicalparameters, and are thus of paramount importance in underground flow problems.Chemical reactions may alter the local properties of the porous media as wellas the fracture walls, changing the flow path and possibly occluding someportions of the fractures or zones in the porous media. To solve numericallythe coupled problem we propose a temporal splitting scheme so that theequations describing each physical process are solved sequentially. Numericaltests shows the accuracy of the proposed model and the ability to capturecomplex phenomena, where one or multiple fractures are present.
