The dynamo action, which is of importance in the study geomagnetism mechanism, considered to be caused by convection structure formed inside a rotating spherical shell. This elongated rotation axis generated action both heat and on fluid In this study, we analyzed thermal such shell attempted understand phenomenon convective structure. It known that each value Prandtl number, Ekman number Rayle...

Abstract The aim of the study is to analyse axisymmetric free vibration layered cylindrical shells filled with a quiescent fluid. fluid assumed be incompressible and inviscid. equations vibrations shell fluid, on longitudinal transverse displacement components are obtained using Love’s first approximation theory. solutions functions in separable form obtain system coupled differential terms fun...

The present paper deals with the experimental and computational study of axial collapse of the aluminum metallic shells having combined tube-frusta geometry between two parallel plates. Shells were having bottom two third lengths as frusta and remaining top one third lengths as tube. Shells were compressed to recognize their modes of collapse and associated energy absorption capability. An axis...

Thorough understanding of the behaviour core–shell microparticles with a liquid core is essential for determining their performance in applications under different operation conditions. This paper reports particles thermal and mechanical loads. First, we formulated an analytical model heating process microparticle core. Next, utilised axisymmetric elastic spherical shell upon compression to des...

We use detailed radiative transfer models to investigate the differences between the Star-Obvious Low-level-Elongated proto-planetary nebulae (SOLE PPNs) and DUst-Prominent Longitudinally-EXtended proto-planetary nebulae (DUPLEX PPNs) which are two subclasses of PPNs suggested by Ueta, Meixner & Bobrowsky (2000). We select one SOLE PPN, HD 161796, and one DUPLEX PPN, IRAS 17150−3224, both of wh...

We present results from a numerical investigation of the localization of deformation in thin elastomeric spherical shells loaded by differently shaped indenters. Beyond a critical indentation, the deformation of the shell ceases to be axisymmetric and sharp structures of localized curvature form, referred to as “s-cones,” for “shell-cones.” We perform a series of numerical experiments to system...
