Turbulent burning velocity is one of the most relevant parameters to characterize premixed turbulent flames. Different correlation has been proposed estimate this parameter. However, them have obtained using experimental data at atmospheric pressure or higher. The present study focused on obtaining a for sub-atmospheric pressure. was experimentally calculated burner method, where premix flames ...

Lithium-ion battery is a new type of clean energy. Due to manufacturing defects, improper use, unexpected accidents and other reasons, lithium-ion thermal runaway fire explosion are frequently re-ported, its safety has become an important issue be solved. In this paper, the effect second-generation halon substitute C 2 HF 5 on gas premix flame studied by experiments numerical simulations.The bu...

Nano γAl2O3 has been one of the nanometal oxides that improved characteristics biodiesel. The effect nanoparticles addition on premixed flame combustion is investigated with an experiment laminar speed Calophyllum inophyllum methyl ester 30% and 70% petrodiesel mixtures, at atmospheric pressure preheated temperature T = 473K. added to CIME30 biodiesel were 0ppm, 100ppm, 200ppm, 300ppm. Experime...

Nyamplung (Calophyllum Inophyllum) is an environmentally friendly alternative fuel that can be used to replace the consumption of fossil fuels. The purpose this experiment was analyze effect magnetic fields on premixed flame biodiesel from Calophyllum Inophyllum, experiments were carried out a bunsen burner. Fuel evaporation uses temperature 473 K and equivalent ratio between ϕ 0.7; 0.8; 0.9; 1...

The research was administered in order to spot the miticidal effect of wild grown plant namely Ferula oopoda against mites that destroy leaf tissue and also colour fruit trees. theme get herb’s (1) aerial, stem root part about 1 kg soaked for 7 days then extract oil by help vaccum rotary evaporator, extracted is allowed stay a day HCl (0.2M), solution filtered some charcoal added filtrate now, ...

Using lightweight fire-rated board (LFRB) presents cost-effective opportunities for various passive fire protection measures. The aim of the project is to develop an LFRB with enhanced resistance, acoustic properties, and mechanical properties. These properties were determined using a Bunsen burner, furnace, energy-dispersive X-ray, impedance tube instrument, Instron universal testing machine. ...

In the present study, we have formulated the G equation concept for large-eddy simulation (LES) of premixed turbulent combustion. The developed model for the subgrid burning velocity is shown to correctly reflect Damköhler’s limits for largeand small-scale turbulence. From the discussion of the regime diagram for turbulent premixed combustion, it is shown that given a particular configuration o...
