This paper investigates the impact of homogeneous-heterogeneous reactions on flow between coaxial cylinders with heat generation/absorption. From an engineering perspective, in energy absorber design for shrinking and expanding a circular metal tube production extruding materials by stretching designing great care is necessary to regulate skin friction transfer rate. Studying processes confined geometries enhances basic knowledge chemical kinetics fluid dynamics. Researchers may increase efficiency/heat activities systems optimized analysing effects flow. Both cost reductions higher-quality products result from this optimization. research yield insights far-reaching implications across multiple disciplines. The modelled equations are transformed into ordinary differential employing apt similarity transformations obtained solved using collocation method Probabilists' Hermite polynomial. Graphs illustrating variation velocity, thermal, concentration profiles have been plotted influence various parameters. curvature parameter causes velocity thermal profile upsurge. rise source/sink improves transport. As heterogeneous homogeneous parameters upsurge, decreases.
