fluids for various industrial applications because of their excellent thermal performance. this study analytically and experimentally examines the effects of nanoparticle dispersion on the entropy generation of eg–al2o3 nanofluid flows through a helical pipe as a heat exchanger under constant wall heat flux thermal boundary condition in laminar regime. it is found that adding nanoparticles impr...

We performed high-resolution simulations of a sample of 14 galaxy clusters that span a mass range from 5 × 1013h−1 M⊙ to 2 × 1015h−1 M⊙ to study the effects of cosmic rays (CRs) on thermal cluster observables such as X-ray emission and the Sunyaev-Zel’dovich effect. We analyse the CR effects on the intra-cluster medium while simultaneously taking into account the cluster’s dynamical state as we...

In this article, curvature effects on elastic thermal buckling of double-walled carbon nanotubes under axially compressed force are investigated using cylindrical shell model. Also, the small scale effect is taken into account in the formulation. The dependence of the interlayer van der Waals (vdW) pressure on the change of the curvatures of the inner and outer tubes at that point is considered...

A model of fractional-order of thermoelasticity is applied to study a 2D problem of mode-I crack in a fibre-reinforced thermal environment. The crack is under prescribed distributions of heat and pressure. The normal mode analysis is applied to deduce exact formulae for displacements, stresses, and temperature. Variations of field quantities with the axial direction are illustrated graphically....

in this study, pyrite was produced by hydrothermal precipitation from the reaction between feso4 and na2s2o3 at high pressure and high temperature in a stirred reactor. the solid product was purified by means of solvent extraction to remove sulfur. powder was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and thermal analyses. results indicated that pyrite was prod...
