The subject of heat transfer in oil reservoirs has gained huge attention, due to its diverse range of applications in petroleum reservoir management and thermal recovery for enhanced oil recovery. Thermal recovery methods entail the addition of heat energy into the reservoir through injection...
A detailed investigation is made to study the effect of the presence of gangue materials like
SiO2, Al2O3 and P2O5 on the reducibility of iron ores in the blast furnace and sponge iron/DRI plants. The shatter index and abrasion index are found to improve marginally with increased content of the...
The effect of
20 organoclay content on fire retardancy, mechanical and chemical properties of dried films of halogen-free alkyd resins synthesized from
20 organoclay and...
A yttria-stabilized zirconia (YSZ, 8 mol %
) membrane was prepared employing zirconium n-propoxide as a precursor via sol–gel method. Unlike conventional methods, hydrolyzing water was slowly released in this method through esterification of 1-propanol...
In this work, cheap and effective nanocomposite material has been synthesized by mixing natural bentonite (B) with 5 % multiwall carbon nanotubes followed by heat treatment to 650
C in the inert atmosphere. It makes a potentially attractive adsorbent of rhodamine dye (RhB)...
Sudden flow changes in confined pipe systems generate transient flow (waterhammer) conditions accompanied with very high or sometimes very low pressures traveling back and forth in the system. Depending on the magnitude of those pressures, pipe collapse or pipe bursting may take place at the...
This article presents the effect of palm oil fuel ash as a supplementary cementitious material on chloride penetration and microstructure of blended cement paste. Palm oil fuel ash (POFA) was ground to obtain two finenesses: one was the same size as the cement and the other was smaller than the...
The paper intends to present a design of a double-blade mixer for the purpose of reinforce concrete mixing quality. The result of comparison experiment on mixing quality of three different types of concrete with the use of different mixers shows that mixing quality of the concrete using a...
High-intensity noise not only hurts body and mental health of workers, but also covers sound signs of accidence. To increase the sound absorption and noise reduction performance of axial auxiliary fan noise silencers, the noise strength and frequency distribution of the ambient medium casing of...
Nowadays, photocatalysis has demonstrated to be a reliable solution in order to purify the atmosphere from the pollutants originated by vehicular traffic. Owing to the primary importance of this problem, the potential of innovative photocatalytic techniques, dealing with the immobilization of...
