flow simulation in a trough or pipe

摘要

A method of simulating transport of a fluid for causing a dissolution process of at least a part of a material of a material formation surrounding the conduit, the conduit having a conduit radius; the method comprising establishing a transport model of fluid transport along a longitudinal axis of the conduit, the transport model including a model of a lateral fluid transport away from said longitudinal axis into the material formation; the method comprises calculating an effective conduit radius dependant on at least one parameter indicative of an estimated distribution of flow channels generated in the material formation by the dissolution process.
