This study presents a comprehensive analytical approach to address the complexities of flow and heat transfer in planar Taylor–Couette systems. Utilizing innovative simplifying assumptions conversion variables, we analyze fluid dynamics between two cylinders, where outer cylinder is hotter, inner rotates at higher velocity. Employing cylindrical coordinate system, research derives governing equations for continuity, momentum, energy dimensions under steady-state conditions. These nonlinear partial differential are transformed into set ordinary (ODEs) using specific facilitating more practical analysis flow. The leverages distinct mathematical methods solve ODEs, introducing novel application penalty function replace pressure term, which traditionally used numerical studies. Our findings indicate that with Reynolds number (Re) 900 Prandtl (Pr) 6.9, dimensionless radial velocity approaches zero, validating model. reveals significant tangential gradient cylinders an efficient from cylinder, entropy values decreasing radially outward. Quantitative results include calculated Nusselt numbers 1.58 −0.58 while skin friction coefficients −0.0049 −0.0012, respectively. non-negative corroborate compliance second law thermodynamics, ensuring robustness results. Additionally, delves generation, number, coefficient, offering holistic view dynamics.
