Options for simulating stand-off distances with fire models

Nowadays, fire safety of buildings is crucial, especially in view of the increasing construction in urban areas where buildings are being built in close proximity. Determining the correct spacing distances between buildings is becoming increasingly important as minority developments that are being built at increasing densities increase the risk of fire transmission. This paper focuses on the use of modern fire models, such as the Fire Dynamics Simulator (FDS), to simulate fires and heat spread in confined spaces to optimize building spacing. Fire models allow not only fire risk analysis but also the accurate determination of heat flows, which is essential in determining spacing distances. Important factors in the simulations are the size of the computational cells, the length of the heat transfer and the humidity, which affect the accuracy of the results. The implementation of these models in practice requires sensitivity analysis to achieve optimal results that can make a significant contribution to protecting human lives and minimizing damage. This approach can be used effectively not only in office and commercial buildings, but also in transportation infrastructures such as railway and bus stations, thereby increasing the safety and efficiency of modern construction.
