IMPACT OF GENERATION AND ABSORPTION OF HEAT ON THE FLOW OF BOGER FLUID PAST A CURVED STRETCHING SHEET: A NON-SIMILARITY SOLUTION APPROACH

Abstract. The objective of this effort is to provide a non-similar analysis of the heat transmission and flow of a Boger fluid past a curved stretched surface with the influence of a magnetic field. Boger fluids, on the other hand, are a class of viscoelastic fluids whose viscosity does not change significantly with changes in shear rate. Thanks to this property, they can have significant applications in the oil and gas industry, wherein they can be used to enhance the performance of drilling. Also, these fluids find use in constructing damping systems, which increases the safety and structural integrity of engineering installations. Additionally, exothermic and endothermic chemical reactions are used to investigate the characteristics of mass transport and heat. The curved stretchable surface has been subjected to convective conditions for mass and heat. The boundary layer equations are transformed into a non-similar form to enhance the precision and comprehensiveness of the analysis of flow, heat, and mass transport. The resultant non-similar partial differential equations (PDEs) are numerically solved using the local non-similarity approach by truncating up to the second level. Numerical data are presented graphically to examine the physical parameters’ effects on flow, mass, and thermal transfer. It is important to note that when the solvent fraction parameter rises, the velocity profile rises as well. As the solutal and thermal Biot numbers climb, so does the temperature and concentration profile.
