This paper presents an alternative environment-friendly thermal insulation material for the construction industry. We aimed to produce this building with superior heat resistance properties and comparable strength concrete produced Ordinary Portland Cement. The primary purpose of experimental studies is a basic geopolymeric plate add cellubor polypropylene fibers mortar. In next stage, fiber-re...

We explore the detailed structure of heat release and the energy budget for a freely-propagating lean, premixed hydrogen flame. At lean conditions, the flame is thermodiffusively unstable and spontaneously develops the cellular burning structures, characteristic of this type of flame. The instabilities in the system saturate quickly, resulting in robust, slowly evolving cellular burning feature...

Among the various advanced materials, flame-retardant cellulosic textiles are important as they directly relate to human health and hazards. The use of environmentally friendly coatings is currently one major concerns in textile coating industry. In this work, acrylic acid was grafted onto surface cotton using plasma technology enhance attachment acrylate phosphate monomer. Surface analyses, su...

We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous, isotropic Kolmogorov-type turbulence in an unconfined system. Direct numerical simulations are performed with Athena-RFX, a massively parallel, fully compressible, high-order, dimensionally unsplit, reactive-flow code. A simplified reaction-diffusion model represents a stoichi...

Chlorinated rubber, the addition and substitution reaction product of natural rubber and chlorine gas, is knOWn for its low Water vapor permeability, good chemical resistance, abrasion resistance, corrosion resistance, and flame retardant properties.' Consequently, it is used as a coating component in a.variety of coating applications including marine coatings, swimming pool coatings, and corro...

A flame shape descriptor based on coordinates of edge of a flame is proposed. Artificial Neural Network is used to predict flame image edges .A flame with constant x-coordinate is used in the present study. Y-coordinates of flame edge are predicted using neural network. Recognition experiments were carried out using flame image sampled from a burning candle. The results show a good recognition ...

Firefighters in Taiwan often wear expired protective clothing, which raises concerns regarding their safety. Extending the service life of fire clothing can improve firefighter safety and ensure environmental sustainability. In this study, an analytic hierarchy process was used to understand risk factors should be prioritized design firefighting turnout gear. We surveyed 30 experts field manage...
