Abstract The paper investigated the benefits of having fins that induce swirling flow within an annular passage. importance vortical structures produced using different fin angles and velocities in heat transfer was studied. combination fluid with recirculation on domain not fully understood, this aims to address gap. 10°, 20°, 30° 40° angled were understand changes performance as becomes more ...

   The main purpose of the present investigation is to analyze more comprehensively the size-dependent nonlinear free vibration response of multilayer functionally graded graphene platelet-reinforced composite (GPLRC) nanobeams. As a consequence, both of the hardening stiffness and softening stiffness of size effect are taken into consideration by implementation of the nonlocal str...

Solar-thermal technology based on phase change materials (PCMs) has received a lot of attention as cost-effective and practical way to overcome solar energy intermittency. However, weak photothermal conversion ability complex preparation processes have hindered the application PCMs. In this work, new approach for facile, uniform, firm assembly graphene nanoplatelet (GNP) through reaction oxide ...

The shear response of a model polymer–clay gel is measured using small-angle neutron and light scattering, optical microscopy, and rheometry. As the flow disrupts the transient network that forms between clay and polymer, coupling between composition and stress leads to the formation of a macroscopic domain pattern, while the clay platelets orient with their surface normal parallel to the direc...

we describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. we present a new method for computing, electronic transport wave function and greens function of the disordered graphene. in this method, based on the small rectangular approximation, break up the potential barriers in to small parts. then using the f...
