Structural response of the spiral-welded pipelines buried in different uniform soil types to the strike-slip fault

open access: yesJournal of Pipeline Science and Engineering, 2023
Buried steel pipelines, which are widely used in, often face the threat of Permanent Ground Deformations (PGD) caused by fault crossings. The structural response of the pipeline can be influenced by the pipe-trench-backfill interaction, resulting in ...

Impact of Cattaneo–Christov Heat and Mass Flux on MHD Hybrid Nanofluid Flow Over an Extending Surface With Convective and Mass Flux Effects

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the flow of a magnetized hybrid nanofluid over a permeable stretching surface. The mass and thermal transport within the system is regulated using the Cattaneo–Christov flux theory. The fluid is additionally subjected to thermophoresis, chemical reaction, Brownian motion, and activation energy effects.
