Abstract The instabilities of fluid in the liquid metal battery (LMB) can easily cause a short circuit and lead to safety accidents, which have become bottleneck LMB industrial applications. In this case, structure named grid-structure (GS) based on inner cavity has been used suppress instabilities. Based OpenFOAM-4 x numerical simulation, we analyzed critical electric potential basic structure...

Chemical looping combustion of biomass is a promising carbon capture technology due to its inherent CO2 separation advantage. However, complete fuel conversion, particularly volatiles conversion for biomass, usually not achieved in the reactor. A novel concept named distributor (VD) has been proposed and tested cold-flow fluidized-bed, which shows good potential achieve more uniform horizontal ...

The classic first-order thrust approximation for solar sails is analytically extended to include the effects of secondary reflections and generalized in a practical Finite Element Model (FEM) based routine. Examination and inclusion of secondary reflection forces are shown to grow increasingly non-trivial as the deformation becomes more extreme. The approach taken herein does not address the “b...

Microstrip antennas are widely used in a broad range of military and commercial applications due to its low cost, low profile, easy fabrication and light weight. But this kind of antenna also has some drawbacks. For example, the diffraction of surface waves at the edge of finite grounded substrate decreases the antenna efficiency and degrades the antenna pattern [1]. In the phased array antenna...

Response surface methodology (RSM) is a statistical method useful in the modeling and analysis of problems in which the response variable receives the influence of several independent variables, in order to determine which are the conditions under which should operate these variables to optimize a corrugated box production process. The purpose of this research is to create response surface mode...

In the present article, a numerical study is performed to investigate the crushing behavior of cylindrical and conical corrugated composite tubes. Different aluminum foams are applied to the proposed structures in order to offer an excellent energy absorption capacity. The crushing behavior of tubes are evaluated in terms of two parameters: SEA (specific energy absorption) and CFE (crush force ...

Multifunctional composite panels for flame retardant and thermal insulation have not yet been studied. In the current study, we prepared sandwich sheets by using continuous glass fiber polypropylene prepreg tape compared properties of different fillings. Corrugated panels, featuring a corrugated space filled with materials, were their mechanical are tested verified. Determining two structural p...
