To ensure reliable results, the fire simulation requires in-depth knowledge, for example, in flow mechanics, thermodynamics and heat transfer. As fire simulation plays a significant role in our most important assignments, we are particularly invested especially in ensuring that KK-Palokonsultti Oy has enough highly trained experts who have the skills required for fire simulation. This allows us to offer our customers the best know-how in the industry.<\/p><h2>Simulation software<\/h2><p>To calculate the simulations we use comprehensively validated and verified open source software <a href=\"https:\/\/pages.nist.gov\/fds-smv\/\">Fire Dynamics Simulator<\/a> (FDS). FDS is a flow calculation software developed to simulate fires. Its operation is based on the numerical solutions of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Navier%E2%80%93Stokes_equations\">Navier-Stokes equations<\/a>, which describe the motion of viscous fluids i.e. liquids and gases, taking into account, inter alia, the conservation of momentum, energy and mass. The international development of the simulation software is the responsibility of the US Department of Commerce<a href=\"https:\/\/www.nist.gov\/\"> NIST<\/a> (National Institute of Standards and Technology). Previously, the program was developed in close cooperation with the Finnish<a href=\"https:\/\/www.vttresearch.com\/fi\"> VTT<\/a> (Technology Research Center VTT Oy). Today, VTT no longer actively participates in the development of FDS&#8217;s fire calculation section, but continues to develop and maintain FDS&#8217;s evacuation calculation section FDS + Evac.<\/p><h2>Fire simulation<\/h2><p>The first step in fire simulation is a three-dimensional model created from the geometry of the building, within which flow computational phenomena occur. Next, a fire scenario to be examined is created, with the descriptive parameters fed into the simulation model. The model includes, on a case-by-case basis, flow surfaces, fire-fighting equipment like fire sprinklers, control logic and measuring points. When the simulation model is completed, it will be transferred to our state-of-the-art computers for calculations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a5d00ce elementor-widget elementor-widget-image\" data-id=\"a5d00ce\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px.png\" data-elementor-open-lightbox=\"yes\" data-elementor-lightbox-title=\"KK-Palokonsultti Oy - fire simulation example (PyroSim)\" data-e-action-hash=\"#elementor-action%3Aaction%3Dlightbox%26settings%3DeyJpZCI6ODYyNSwidXJsIjoiaHR0cHM6XC9cL3d3dy5ray1wYWxva29uc3VsdHRpLmNvbVwvd3AtY29udGVudFwvdXBsb2Fkc1wvMjAyMVwvMDhcL2trLXBhbG9rb25zdWx0dGktb3lfcHlyb3NpbS1leGFtcGxlXzE5MjB4MTA0MHB4LnBuZyJ9\">\n\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"768\" height=\"416\" src=\"https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px-768x416.png\" class=\"attachment-medium_large size-medium_large wp-image-8625\" alt=\"KK-Palokonsultti Oy - fire simulation example (PyroSim)\" srcset=\"https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px-768x416.png 768w, https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px-300x163.png 300w, https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px-1024x555.png 1024w, https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px-1536x832.png 1536w, https:\/\/www.kk-palokonsultti.com\/wp-content\/uploads\/2021\/08\/kk-palokonsultti-oy_pyrosim-example_1920x1040px.png 1920w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ed4bfd8 elementor-widget elementor-widget-text-editor\" data-id=\"ed4bfd8\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Example of a simple scenario in PyroSim software.

For example, simulation can be used to compare the efficiency of mechanical and gravity smoke extraction or examine the effect of automatic smoke extraction on the security level of a building. By modeling the airflow created by directional pressure fans, which are often used in parking garages, we can study the actual range of influence of the fans and ensure the functionality of the planned smoke extraction.<\/p><h2>Performance based review of fire resistance of structures<\/h2><p>The structures can be designed for sufficient fire resistance by simulating and analyzing the assumed fire scenarios. Fire simulation can reliably measure the warming of structures, and thus ensure the durability of the planned implementation in a real fire. <a href=\"https:\/\/www.kk-palokonsultti.com\/en\/fire-safety-in-depth-information\/performance-based-fire-safety-design\/\">A site-specific fire resistance review<\/a> allows for accurate sizing of structures and helps designers select the right building materials for the site. When materials with sufficient fire resistance are used in exactly the right amounts and combinations, money and raw materials are saved, and therefore also nature &#8211; without compromising on safety!<\/p><h2>Fire Design Guidelines for Load-Bearing Steel Structures<\/h2><p><strong>Guidelines for the fire design of load-bearing steel structures when automatic fire suppression systems are used as fire protection<\/strong> have been prepared to provide an overall overview and to clarify the sprinkler protection of load-bearing structures implemented through certification and performance-based fire design. There has been varied practice in the field, particularly when certification has been used, which has been the main reason for the need for this guideline. The guideline also addresses general principles related to sprinkler protection of load-bearing structures carried out using performance-based fire design.
