A micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. Governing equations were solved base on the finite volume method with FLUENT software. In upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. Two sections were separated with solid part which played as heat exchanger and trans...

In marine storage and transportation, the sloshing of liquid oxygen disturbs thermodynamic equilibrium induces stress on tank walls. Numerous problems are associated with mechanism demand a detailed investigation. this study, numerical model is developed by coupling Eulerian framework algebraic interface area density (AIAD) method while considering interphase drag force to investigate thermal b...

Sloshing refers to a certain kind of fluid movement that changes as it progresses. It possesses properties are both nonlinear and exceedingly unpredictable, these affect the tank wall. This effect may lead structural wear, which in turn can cause fail. Benzene gasoil liquids used test sloshing liquid accompanying pressure on wall caused by baffles partially full tanks. To attain this, modeling ...

Successful surgical correction for anomalous origin of the left coronary artery from the pulmonary artery in a 4-year-old child is reported. An aortopulmonary fistula was created and a pericardial baffle was inserted within the pulmonary artery to connect the fistula to the ostium of the left coronary artery. The clinical, haemodynamic, and angiographic features of the anomaly are presented. Th...

In this paper, a metal–insulator–metal (MIM) surface plasmon waveguide structure is proposed and numerically investigated. It composed of square-ring cavity with silver baffle, an isosceles triangle cavity, bus baffle. The results show that the can produce triple Fano resonances be independently tuned by changing structural parameters. detection refractive indexes at different positions in was ...

• Second law scrutiny of NEPCM suspension inside a circular cylinder is inspected. The cold possesses wavy baffle which acts as heater. amplitude hot have potential to be changed. whole system assumed affected by Cattaneochristov heat flux model. governing equations been solved via the finite element method (FEM). Free convection and second nano-encapsulated phase change material (NEPCM) along ...

Windage power loss (WPL) is significant and cannot be neglected in a study on transmission efficiency reducing the energy consumption of high-speed gear. The influence mechanism baffle reduction WPL needs to further studied. Based computational fluid dynamics (CFD) technology, this paper puts stress analyzing axial radial baffles viscous pressure effects with groove structures WPL. numerical ca...
