Isolation rooms are used in many infectious diseases hospitals to treat seriously ill patients. An important feature of these rooms is that they maintain negative pressure, which helps keep contaminants in the room and prevent them from spreading outside the room. Mathematical modeling of the stationary ventilation process using computational fluid dynamics was carried out within the framework of the OpenFOAM package. The three-dimensional model of the infectious ward is a hexahedron with dimensions 4x4x2.6 m3, inside of which there are three beds with three immobile patients. The computational mesh was created using the blockMesh and snappyHexMesh utilities, and the discretization of the system of basic equations representing the laws of conservation of mass, momentum and energy was carried out using the control volume method. A study was carried out of the influence of a negative output boundary condition for pressure on the hydrodynamic characteristics of air flow in a model of an infectious diseases ward.
