Abstract Sodium-alginate (SA) based nanofluids represent a new generation of fluids with improved performances in terms
of heat transfer. This work examines the influence of the nanoparticle shape on a non–Newtonian viscoplastic
Cu–nanofluid pertaining to this category. In particular, a stretching/shrinking sheet subjected to a transverse magnetic field is considered. The proposed Cu–nanofluid consists of four different nanoparticles having different
shapes, namely bricks, cylinders, platelets, and blades dispersed in a mixture of sodium alginate with Prandtl
number Pr = 6.45. Suitable similarity transformations are employed to reduce non–linear PDEs into a system
of ODEs and these equations and related boundary conditions… More >

Abstract Sixteen groups of comprehensive tests have been conducted to investigate the modifications in the physical properties of a weak expansive soil due to the addition of a cement jute fiber. The tests have been conducted to analyze
the liquid plastic limit, the particle distribution and the free expansion rate. The results show that: (1) With an
increase in the cement-jute fiber content, the free expansion rate of the modified expansive soil gradually
decreases, however, such a rate rebounds when the fiber content exceeds 0.5% and the cement content exceeds
6%. (2) With an increase in the cement percentage, the particle… More >

Abstract Oxygen-reducing air flooding is a low-permeability reservoir recovery technology with safety and low-cost advantages. However, in the process of air injection and drive, carbon in the air is oxidized through the crude oil reservoir to generate CO2, and this can cause serious corrosion in the recovery well. In this study, experiments on the
corrosion of J55 tubular steel in a fluid environment with coexisting O2 and CO2 in an autoclave are presented. In
particular, a weight loss method and a 3D morphometer were used to determine the average and the local corrosion rate. The corrosion surface morphology and composition were… More >

Abstract In order to ensure the safe operation of the compressors used in water chillers, in the present study some interlock
protections have been added to the related design. These include a low pressure protection, a high pressure protection, an exhaust temperature protection and a differential pressure protection. Some tests have been conducted
by tuning the saturation suction and exhaust temperatures of the compressor through adjustment of the cold
source outlet temperature and the ambient temperature. The results show that the ambient temperature increases
with decreasing device load and increasing fan speed under the same saturated suction temperature; the device
refrigerating… More >
