description: The work is devoted to obtaining initial information about the effect of passive displacement cooling in a ventilated room using the example of a two-dimensional model problem. Using the commercial code ANSYS Fluent version 2019 R3, the flow in a rectangular room with a simplified human fuel model placed in it is numerically simulated. A simplified model of an air-cooling tube bundle is placed in the space behind the false ceiling. The simulation is based on the solution of the Reynolds-averaged Navier-Stokes equations. An analysis is carried out on the resulting solution of the turbulence model and the spatial resolution of the computational grid. The influence of the position of a simplified human model, the number and location of holes in the suspended ceiling, as well as the length of the wall panel on the flow and heat transfer is investigated.
