A hybrid nanofluid model is considered to comprise two different types of nanoparticles, Go and Ag , with kerosene oil used as a base fluid. To study the phenomenon of thermal conduction, a modified version of Fourier’s law model is adopted because in the power-law model, the thermal conductivity depends on the velocity gradient. A system of nonlinear ordinary differential equations is obtained by considering the similarity transformations over the obtained rheological system of partial differential equations which is then tackled by a well-known numerical approach, i.e., the bvp4c MATLAB technique. The rheological impacts of the power-law index, solid volume fraction, film thickness, Eckert number, and modified Prandtl number on temperature and velocity fields are graphically discussed and illustrated. In the presence of nanoparticles, the temperature of the working fluid is enhanced and the power-law index has an inverse relation with the velocity of the hybrid nanofluid.

The laminar wall jet of classical Glauert type is extended to the Casson fluid model considering the flow to be along a flat permeable surface. The roles of velocity slip, wall temperature, and mass transfer on the fluid flow and rate of thermal exchange are investigated. The outcomes for momentum and thermal fields, skin friction and heat transfer gradient are obtained analytically with numerical solutions of the suction-far stream velocity expression. It is noted that mass transfer and velocity slip have significant effects on the flow of fluid and heat transfer. Thermal profile varies significantly for increasing Prandtl values with small suction.

UMO-2019/35/N/ST5/02532. AB - Two types of carbon, i.e. carbon electrode (CE) and carbon furnace lining (CFL) were modified with silicon oxycarbide (SiOC) or carbon nanotubes-containing SiOC (SiOC/fCNT) by means of polysiloxane impregnation and pyrolysis. The two carbon materials differed in pore size and in surface chemical state. The impact of these factors on the infiltration efficiency was investigated by comparing the physical, electrical and mechanical properties in samples before and after infiltration. It was shown that SiOC phase is formed in the CE macropores, leading to a reduction in the average pore size from 8.2 to 5.3 mu m, and in porosity from 12.6 to 7.3%. For CFL, which contains both meso- and macropores, the observed changes in porosity are smaller. Introducing fCNT into the resin changes its surface nature from hydrophobic to hydrophilic. This modified solution better wets a CE surface containing functional groups and provides an enhanced interface contact between this carbon and SiOC. The fCNT-modified SiOC phase improves the compressive strength and modulus of both types of carbon. The electrical resistivity of CE modified with SiOC/fCNT is slightly higher, whereas for CFL it does not change. Oxidation tests in air up to 1000 degrees C showed a significant reduction in the mass loss of both carbon materials after their modification with pure SiOC and SiOC/fCNT. The proposed infiltration procedure can be applied to conventional carbon and graphite technology, in particular to porous carbons containing a macropore fraction.

AB - The aim of this paper is to expand application scope of pea protein isolate by improving its emulsification. Pea protein isolate was ground for different time, and changes in its structure and emulsification properties were studied, and then revealed the influence mechanism of grinding on emulsification. It was found that the beta-sheet of protein decreased from 39.92% to 31.47% after grinding for 20 min, and the pea protein was converted from a solid ball to a hollow ball. So the emulsion flocculation index decreased from 1.01% to 0.29% and the amount of protein adsorbed increased by 4.5%, which showed that the emulsion stability of the pea protein was significantly improved. Within a short grinding time (2.5-5 min), the viscosity of the emulsion was increased. Studies had shown that proper grinding treatment made pea protein isolate possess greater potential for an excellent emulsifier. LA - English DB - MTMT ER - TY - JOUR AU - Wei, D. AU - Al-Ashhab, S.

In the self-similar case, the boundary layer system is converted into a third-order nonlinear differential equation depending on two parameters. When one of the two parameters is negative, the existence and uniqueness of normal convex solutions and generalized convex solutions to the boundary layer problem are established by the aid of the Helly selection theorem. The asymptotic behavior of normal convex solutions at infinity is also obtained. (C) 2019 Elsevier Ltd. All rights reserved.

Two different analytical methods, namely Adomian Decomposition Method (ADM) and the Optimal Homotopy Asymptotic Method (OHAM) are used for finding the series solution of the problem. The solutions obtained through two different techniques are compared using graphs and tables and found an excellent agreement. The variants of embedded flow parameters in the solution are analyzed through graphical illustrations.
