The present investigation aims to study the influence of thermal radiation and chemical reaction on the unsteady magnetized flow of Casson fluid with immersed nanoparticles. The flow is past a permeable stretching surface. The nanofluid heat transmission characteristics are described with the Buongiorno model. The governing system of non-linear partial differential equations (PDEs) is converted into non-linear ordinary differential equations (ODEs) with a similarity group of transformations. The reduced ODEs are numerically solved with an effective shooting strategy along with the standard R-K fourth-order method. The graphical illustration for the immerging parameters on non-dimensional velocity, temperature, and concentration is obtained through bvp4c using MATLAB. The code validation is provided by comparing the numerical outcomes of a few parameters with recently published work. The result shows that the thermal radiation boosts the energy supply in the flow field, and hence, the thermal regime enhances quickly. Due to the rise in chemical activity and Schmidt number, the concentration profile declines. The flow velocity declines with higher magnetic flux.

Physical quantities like density (&amp;rho;), pressure (p), and energy (e) are always non-negative. It is one of the essential qualities a scheme (numerical solver) to maintain the positiveness of these quantities in obtaining the solution of the Euler's equations (or diffrential equations) for inviscid fluid flow. The central solvers add explicitly numerical dissipation to obtain the solution. In this research work, the minimum amount of numerical disspation requirement is analytically obtained for 1D compressible Euler equations by enforcing the positivity criterion to have realistic density, pressure, and internal energy. The positivity analysis of explicit central solver is carried out analytically in 1D for compressible Euler equations to have realistic density, pressure, and energy under the Courant-Friedrichs-Lewy (CFL) condition with Courant number 1. The minimum numerical dissipation criterion obtained in 1D Euler's equations for an explicit solver is a function of the parameters, such as fluid velocity, flow Mach number, and specific heat ratio (&amp;gamma;). The Lax and Friedrichs (L-F) scheme always provides real physical solutions because it has more numerical dissipation than the minimum numerical dissipation required to satisfy positivity. A new positivity-preserving numerical scheme is developed for compressible Euler's equations based on the minimum numerical dissipation in the finite volume framework and tested on the standard test cases in 1D and 2D.
