Semi-structural bonded joints of steel components are exposed to long-term stresses in addition water diffusion, temperature changes and varying external forces during operation. These hygro-thermomechanical loadings lead successive degradation stiffness strength due damage resulting from chemical aging fatigue processes, causing failure the joint when its service life is reached. In following ...
This work reports the results of the theoretical investigation of nonlinear dynamics and spiral wave breakup in a generalized two-variable model of cardiac action potential accounting for thermo-electric coupling and diffusion nonlinearities. As customary in excitable media, the common Q10 and Moore factors are used to describe thermo-electric feedback in a 10° range. Motivated by the porous na...
We proposed a general formulation of the successive linearization method for solving highly nonlinear boundary value problem arising in rotating disk flow. The problem was studied under the effects of partial slip, thermal diffusion, and diffusion-thermo. The governing fundamental conservation equations of mass, momentum, angular momentum, energy, and concentration are transformed into a system...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The aim of this is paper is to investigate on the effects of viscous dissipation and diffusion thermo on an unsteady MHD flow with an inclined oscillating plate started impulsively. The effects with a variable temperature and mass diffusion are obs...
This paper presents a three-dimensional heat transfer analysis of flat-plate oscillating pipe (OHP). To enhance implementation OHPs in various applications, it is important to understand the comprehensive phenomena that include thermal diffusion whole structure and hydraulics channel. We developed an OHP model includes effect thermo-fluid behavior. The was validated with experimental results al...
We designed and fabricated a four-channel reconfigurable optical add-drop multiplexer based on silicon photonic wire waveguide controlled through thermo-optic effect. The effective footprint of the device is about 1000 x 500 microm(2). The minimum insertion loss is about 10.7 dB and the tuning bandwidth about 17 nm. The average tuning power efficiency is about 6.187 mW/nm and the tuning speed a...
background: recently the role of platelets in the tissue regeneration, wound healing and prevention and control of infections has been reported. we aimed to assess the antimicrobial effect of human platelet concentrate against six bacteria, commonly found in wound and hospital-acquired infections. methods: in vitro susceptibility to samples of 10 random human platelet concentrates was determine...
This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented dual solutions for the flow over a rotating cone and a rotating flat plate cases. Similarity var...
We study the solvability and homogenization of a thermal-diffusion reaction problem posed in a periodically perforated domain. The system describes the motion of populations of hot colloidal particles interacting together via Smoluchowski production terms. The upscaled system, obtained via twoscale convergence techniques, allows the investigation of deposition effects in porous materials in the...
