transport.m.chanism in chemically reactive hybrid nanofluid flow containing gyrotactic micro-organisms over a curved oscillatory surface

引用

Applied mathematics and mechanics(English Edition) 2025年第1期46卷 177-192页

作者： m.NAVEED m.ImRAN t.ASGHAR Z.ABBAS Department of mathematics Division of Science and TechnologyUniversity of Education Department of mathematics The Islamia University of Bahawalpur

this paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrotactic microorganisms towards a curved oscillatory surface. the influence of magnetic fields is also inspected in terms of their physical characteristics. to depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the characteristics of both heterogeneous and homogeneous chemical reactions are also incorporated. Utilizing a curvilinear coordinate syst.m. the flow problem is formulated as partial differential equations(PDEs)for moment.m. concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAm).the effects of significant flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and t.m.erature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and t.m.erature fields are enhanced as the values of the solid volume fraction variables *** is also verified that the concentration rate field decreases as the values of the homogeneous reaction strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous reaction strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

Engineering Hong Kong Polytechnic University Hung Horn Hong Kong China

to improve the sliding wear resistance of AZ91D magnesium alloy, Cu-based amorphous composite coatings made of Cuatti34Zr11Nis and Cu47ti34Zr11Ni8＋20 wt pct SiC powders were fabricated on AZ91D magnesium alloy by laser cladding, respectively. SEm （scanning electron microscopy）, EDS （energy dispersive X-ray spectroscopy）, XRD （X-ray diffraction） and t.m.（transmission electron microscopy） techniques were employed to study the phases of the coatings. the results show that the coatings mainly consist of amorphous phase and different intermetallic compounds. the reason of formation of amorphous phase and the function of SiC particles were explained in details.

Fatigue reliability analysis of fixed offshore structures:A first passage problem approach

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第11期7卷 1839-1845页

作者： mADHAVAN PILLAI t.m. VEENA G. Department of Civil Engineering National Institute of Technology Calicut 673601 India

this paper describes a methodology for computation of reliability of members of fixed offshore platform structures, with respect to fatigue. Failure criteria were formulated using fracture mechanics principle. the problem is coined as a “first passage problem”. the method was illustrated through application to a typical plane frame structure. the fatigue reliability degradation curve established can be used for planning in-service inspection of offshore platforms. A very limited parametric study was carried out to obtain insight into the effect of important variables on the fatigue reliability.

the microstructure and wear behaviour of the thermite reaction coating produced by the hybrid laser claddingremelting on AA7075 aluminum alloy for the syst.m. of Al-CuO-SiO2, Al-Cr2O3-SiO2, Al-Fe2O3-SiO2, and Al-tiO2-SiO2 were studied. the results of the X-ray diffraction （XRD） analysis show that in all the four reaction coatings, α-Al2O3 and γ-Al2O3 phases were present at the top surface, together with various intermetallic phases, the corresponding reduced metal and Al phase in the fusion zone. Under the dry sliding condition, the wear resistance, in terms of weight loss, of the laser-clad specimens was considerably higher than that of the untreated specimen. the predominant wear mechanism of the former specimens was abrasive wear, while for the latter, it was the adhesive wear that prevailed.

StUDY OF RAY IRRADIAtION ON DIAmOND-LIKE CARBON FILmS

引用

Acta metallurgica Sinica(English Letters) 2002年第1期15卷 26-32页

作者： G.A. Liu t.m. Wang E.Q Department of Applied Physics Southwest Jiao Tong University Chengdu 610031 China Beijing University of Aeronautics and Astronautics Beijing 100083 China Department of Physics Lanzhou University Lanzhou 730000 China

Diamond-like carbon (DLC) films have been deposited on glass substrates usingradio-frequency (rf) plasma deposition method. Gamma -ray, ultraviolet (UV) ray were used toirradiate the DLC films. Raman spectroscopy and infrared (IR) spectroscopy were use to characterizethe changing characteristics of SP^3 C-H bond and hydrogen content in the films due to theirradiations. the results show that, the damage degrees induced by the UV ray on the SP^3 C-H bondsare much stronger than that by the gamma -ray. When the irradiation dose of gamma -ray reaches 1 OX10^4 Gy, the SP^3 C-H bond reduces about 50 percent in number. the square electrical resistance ofthe films is reduced due to the irradiation of UV ray and this is caused by severe oxidation of thefilms. By using the results on optical gap of the films and the fully constrained network theory,the hydrogen content in the as-deposited films is est.m.ted to be l0-25at. percent.

tHEtOP QUARK

引用

Chinese Physics C 2016年第10期40卷 660-681页

作者： t.m. Liss F. maltoni A. Quadt the City College of New York Univ. Catholique de Louvain Univ. GSttingen

A. Introduction the top quark is the Q = 2/3, t3 = ＋1/2 member of the weak-isospin doublet containing the bott.m.quark （see the review on the ＂Electroweak model and Constraints on New Physics＂ for more information）. Its phenomenology is driven by its large mass. Being heavier than a W boson, it is the only quark, that decays semi-weakly, i.e., into a real W boson and a b quark. therefore, it has a very short lifet.m. and decays before hadronization can occur. In addition, it is the only quark whose Yukawa coupling to the Higgs boson is order of unity. For these reasons the top quark plays a special role in the Standard model （Sm） and in many extensions thereof.
