A scientific report of singular kernel on the rate-type fluid subject to the mixed convection flow

The response of inhomogeneous fluids whose material properties are strongly interconnected with mean normal stress and shear rate; such phenomenon undergo to rate constitutive-type theories within thermodynamical aspects. In this context, the thermodynamic approach for modeling a class viscoelastic so-called Oldroyd-B fluid is investigated through singular kernel. This because role kernel has become imperative due wide applications rate-type subject mixed convection flow. To have systematical molecular dynamics fluid, temperature distribution, velocity profile, Nusselt numbers been explored by invoking Laplace transform on governing equations. Owing strengthening physical parameters, enhancement convective heat transfer emphasized based relaxation as well retardation phenomenon. Additionally, evaluation thermal flow characteristics resulted in discovering more evolutionary mechanisms considered problem
