This paper describes the application of Computational Fluid Dynamics (CFD) to predict velocities and temperature distributions induced by a fire in a Steckler’s experimental data [1]. The experimental data of different fire loads is taken as case study for present investigation. The experiments of Steckler’s compartment fire were conducted to investigate fire-induced flows through the opening in a compartment of size 2.8 m × 2.8 m × 2.18 m (height). The compartment has a doorway opening of 0.74 m × 1.83 m to account the ventilation condition. A porous gas burner is flushed at the floor in the centre of the room with the diameter of 0.3m in the compartment. With the above experimental data, simulation studies were performed with combustion modelling using commercial code of ANSYS CFX-5. The comparison of simulation results of fire field models with experimental domain for different strengths of fire 31.6, 62.9, 105.3 and 158.0 kW is reported. The boundary conditions of the simulation are kept constant, only fire strength is changed to see the performance of the CFD tool. The door centreline temperature, velocities and room corner temperatures are predicted and compared with experimental data as well as with FDS. The results are in good agreement with the experimental data.","PeriodicalId":12289,"journal":{"name":"Fire Science and Technology","volume":"66 1","pages":"35-46"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81451766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is noted that it is impossible to predict the fire performance of sandwich panels when they are actually used in real buildings only from small scale tests such as ISO 5660-1. This is not a deficiency regarding the ISO 5660-1 as a test method but it is difficult to use the small scale results on a horizontal surface (100 mm by 100 mm) in order to predict the fire performance of sandwich panels in real applications.. The reason is that in actual building fires, both ceilings and walls made of sandwich panels are heated from various directions and weak points are the joints and seals which can never be evaluated with a small-scale test. Therefore, in this study, the authors firstly modified ISO/TS 17431 model box test with free-standing specimens, referring to ISO 13784-1, and different types of sandwich panels were chosen to be the specimens, and the results are discussed comparing with ISO 5660-1 results.

There, supertall buildings, large atria, deep underground subway stations, long tunnels and huge green architectural features are constructed. Fire engineers will be expected to design, build and maintain 'traditional' fire engineering systems; they will also need to handle fire engineering approach for performance-based design, which projects having difficulties to comply with the fire codes adopt. Consequently, fire engineering evolved from vocational training to a high-level engineering discipline. The necessity of providing higher education at degree and above levels in fire engineering will be discussed in this paper. Problems encountered in performance-based design which are caused by an inadequate number of well-trained engineers will also be pointed out. The education programmes which are running in Hong Kong now will be used as an example. The subjects on fire engineering are described. Two points to note are discussed. Firstly, in contrast to other engineering subject disciplines, fire engineering must integrate basic fire science with real-life practices. Integration of professional experience in conjunction with fundamental fire science is essential. Professional accreditation of the fire engineering programmes is very important. Secondly, practicing fire engineering curriculum are mainly designed for solving fire problems encountered in developed countries, not for the ones encountered in South East Asia. Quality teaching on those topics should be provided with in-depth research.","PeriodicalId":12289,"journal":{"name":"Fire Science and Technology","volume":"20 4","pages":"49-62"},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72385551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
