Heat and mass transfer analysis of constitutive model with autocatalytic chemical reaction within the Jeffery–Hamel flow perspective

This article examines the heat and mass transfer capabilities of a constitutive model in thermally evolving steady laminar Jeffery–Hamel flow through convergent-plate channel, including streamwise conduction with step changes uniform wall temperature. A problem simple shear is used to undertake comparative computational analysis thermal behavior viscoelastic fluid subjected autocatalytic processes. The tracked purely radial orientation deployment coupled stresses momentum conservation. solutions for flow, temperature concentration distribution, coefficient obeying complex Oldroyd-B equation converging channel flows are established. impacts radiation, source, chemical reaction as an process included model, which valid fully developed hydrodynamic conditions constant flux imposed at wall. In diverging part where vortex compression predominant topology, there exist patches local compression. On field, modified relaxation retardation parameters show opposing behavior. An exhibits higher interactions nearby vortices divergent allowing structure. characteristics anticipated change homogeneous–heterogeneous transport processes, offering tremendous potential applications associated sectors. deceleration acceleration augment average Nusselt numbers.
