In this analysis, we have developed a new stress tensor of combined fluid models such as Sutterby fluid, Casson and micropolar fluid. The study focuses on flow over curved sheet stretched exponentially. Brownian motion thermophoresis impacts are highlighted considered to very low magnetic Reynolds number with heat generation effect. Based certain assumptions, the mathematical model has been using boundary layer approximations in terms coupled partial differential equations (PDEs). These PDEs transformed from ordinary solved numerical technique. findings presented through graphical tabular data, illustrating governing physical parameters system. Concentration curves show improving phenomena by enlarging values curvature factor. parameter significantly mass transfer, resulting higher rates while simultaneously reducing friction at surface. range factors is 0.1 ≤ β 6.0, 0.0 Υ 5.0, 0.7 P r 10, δ 1 4.0, Ec 10.0, M γ N t 3, b 3. velocity becomes lesser due increasing factor revealed declining enrichment parameter.

ABSTRACT Newtonian heating with a heat source has applications in variety of areas, including exchangers, electronic devices, nuclear reactors, gas cooling systems, ventilated rooms, and industrial processes. In the present numerical investigation, we examine effect an internal temperature‐dependent chemical reaction on transient free convective laminar flow within vertical annulus. The Method Lines is employed to solve governing partial differential equations appropriate boundary conditions. findings were extensively analyzed through plots tables demonstrate impact various fluid features concentration, temperature, velocity profiles. It observed that these profiles increase over time until they stabilize at steady state. Additionally, Schmidt Damköhler numbers are found reduce concentration profiles, whereas Richardson, Biot, mass Grashof have opposite effect. A major investigation revealed increases external transport gives better control parameter.
