... to the increased rate of nucleation of intermediate soot particles, the flame in the presence of alkali metal additives has higher total, luminous, and IR radiation than in the presence of other metal additives. Also, the metallic additives do not significantly change the flame temperature. The results also...

... out to scrutinize the influence of brine salinity, asphaltene concentration, and temperature on IFT. Single and multi-component brines, which in particular compose of NaCl, CaCl 2 , and MgCl 2 salts, and two synthetic oils with 1 and 10 wt% asphaltene content were used at temperatures ranging from 25...

... the concentration of the evaporated droplets around the axis centerline, which enhances the fuel-oxidant mixing rate and raises the flame temperature. Unlike an applied electric force in (−y) direction, an applied electric force in (+y) direction decreases the flame temperature. However, as the primary injection...

...S. H. Pourhoseini; Maryam Ghodrat This study presents a comparative experimental approach to analyze flame temperature, emissions, and radiation behaviors of an oil furnace fueled with nano biodiesel blend fuel containing suspended energetic and non-energetic nanoparticles (NPs). Iron NPs were used...

... of the 5-year study. The ten packers are made of three types of swelling elastomers, are kept in crude oil and saline solutions at room and high temperatures, and are exposed to varying high pressures. Regular logs of readings were maintained over the whole study period. Earlier sealing was observed...

...%) using a temperature-programmed experimental device. The purpose of this research was to examine the oxidation patterns of bituminous coal under different inert conditions. The results showed that: (1) the oxidative heating of the coal underwent two stages: an initial slow heating stage and a fast...

... polymer solutions is affected by temperature. In this study, temperature dependence (25–70 °C) of the viscosity of a partially hydrolyzed polyacrylamide solution, the most widely used EOR polymer for oil field applications, was measured under varying conditions of the polymer solution (polymer...

... and volumetric density in a single step, which tremendously reduces the time and energy consumption compared to that required by the prevailing multistep method. This novel fuel upgrading process can increase the biomass temperature to 473–573 K within tens of seconds to create torrefaction. Studying...

... for characterizing lost circulation using pore-scale dynamic water-based mud (WBM) filtration data. The approaches used in this study include: factorial design of experiment (DoE), hypothesis testing, analysis of variance (ANOVA), and multiple regression analysis. The results show that an increase in temperature...

...Erman Ulker; Mehmet Sorgun; Ismail Solmus; Ziya Haktan Karadeniz In this work, the effect of temperature on the pressure loss for Newtonian fluid in fully eccentric annulus with pipe rotation is investigated. Extensive experiments with water are conducted at Izmir Katip Celebi University (IKCU...

... to be delayed, with the increment in experimental temperature. The influence of mixture velocities on the inversion process could be neglected in the range of mixture velocities that we studied. As well, inversion point obtain by our experiment are best predicted by the correlation of Arirachakaran et al. (1989...

... . The AN for ULSDF and all blends between B2 and B20 for Bio1, Bio2 and Bio3 remained in the range of 0.1 – 0.3 mg KOH g − 1 for all temperatures and throughout the storage period well below the ASTM 6751 limit of 0.5 mg KOH g − 1 . All blends showed a lower increase in AN than any of the base fuels. All fuels were...

... to evaluate the rheological behavior of formate-based fluids as a function of temperature and density. An analytical expression was developed to correlate shear stresses with temperature for general drilling fluids and a special case of this expression results in a greatly simplified expression that is valid...
