Designing smoke alarm systems for modern parking lots of a closed type using mathematical models of processes heat and mass transfer based on the number of fructu

Annotation

Calculation of the smoke alarm system of the parking lot at the stage of outline design or in the preparation of the technical and commercial proposal is preferably carried out on the basis of a simplified analytical model. It is necessary to estimate the error of the results obtained in comparison with the basic CFD model. The most common approach to modeling the movement of flue gases in a room where a fire has occurred is a simulation based on the Froude number. The basic ideas concerning the Froude number and similarity relations in Froude simulation are the same regardless of which variant of the formula formula is used for this criterion. Froude modeling is acceptable for describing the spread of smoke away from the fire, where the flame reaches the ceiling. This approach is permissible based on the regulatory requirements for a fire scenario in a closed parking lot.
