Abstract Computational Fluid Dynamics (CFD) was carried out to analyze pool-fire suppression in rolling stock for two cases. One is single-pool fire simulation in which fire is located in center of rolling stock, the other is multi-pool fire simulation in which fires are located 4.8m from center of, respectively. Six water mist nozzles are installed and equally spaced along rolling stock for each case. It is assumed that pool fire is volume constant heat source, 50kW, for each case. This analysis was performed using DPM (Discrete Phase Model) from Fluent, a commercial CFD code. More >

Abstract We investigated the response of apical and basal actin stress fibers (SFs) and its dependency on cell confluency for endothelial cells subjected to cyclic stretching. Porcine aortic endothelial cells from the 2^nd and 5^th passages were transferred to a fibronectin-coated silicone chamber with 5000–8000 cells/cm²(isolated condition), positioning the cells apart, or with 25,000–27,000 cells/cm²(subconfluent condition), allowing cell-to-cell contact. The substrate was stretched cyclically by 0.5 Hz for 2 h with a peak strain on the substrate that was 15% in the stretch direction and –4% in the transverse direction. The actin filaments (AFs) were stained with rhodamine phalloidin and their… More >

Abstract In this paper, we take the mid-temperature gravity heat pipe exchanger as the research object, simulate the fluid flow field, temperature field and the working state of heat pipe in the heat exchanger by Fluent software. The effects of different operating parameters and fin parameters on the heat transfer performance of heat exchangers are studied. The results show that the heat transfer performance of the mid-temperature gravity heat pipe exchanger is the best when the fin spacing is between 5 mm and 6 mm, the height of the heat pipe is between 12 mm and 13 mm, and the inlet… More >

Abstract The aim of this work is the numerical simulation of the combustion of hydrogen with air in a burner and the numerical solution of local entropy generation rate in the combustion chamber. The effects of equivalence ratio φ and oxygen percentage γ on combustion and entropy generation rates are studied for different φ(ranging from 0 to 1.0) and γ values (ranging from 10 to 30%). The predictions show that the increase of φ (or the decrease of λ ) reduces notably the reaction rate levels. The equations of continuity, of energy and momentum are solved by volume finite using commercial… More >
