In this study, subcritical water was used for the extraction and fractionation of organic atmospheric particulate. Two types of carbonaceous aerosol, diesel exhaust particulate (a relatively nonpolar matrix) and wood smoke particulate (a polar matrix), were sequentially extracted using subcritical water at temperatures ranging from 25°C to 300°C. The importance of each fraction was evaluated us...

in the present work, the simultaneous effects of fuel injection rate and injection of air jet into the combustion chamber on exhaust emissions, combustion process and performance parameters in a direct injection diesel engine were investigated. in order to create an air jet, a design was presented in which a secondary chamber (air cell) was created inside the cylinder and was joined to the main...

an ever-increasing drift of energy consumption, unequal geographical distribution of natural wealth and the quest for low carbon fuel for a cleaner environment are sparking the production and use of biodiesels in many countries around the globe. in this work, jatropha and karanja biodiesels were produced from the respective crude vegetable oils through transesterification, and the different phy...

The toxic smoke production of four rainscreen façade systems were compared during large-scale fire performance testing on a reduced height BS 8414 test wall. Systems comprising ‘non-combustible’ aluminium composite material (ACM) with polyisocyanurate (PIR), phenolic foam (PF) and stone wool (SW) insulation, polyethylene-filled ACM PIR insulation tested. Smoke toxicity was measured by sampling ...

The traditional method has a large control error in the corridor mechanical smoke method. Therefore, multi-task convolutional neural network-based high-rise building is proposed. Through exhaust principle of corridors, threshold set to predict volume corridors. movement corridors simulated according fire dynamics simulator determine turbulence state Input data into network complete Experimental...
