Heat exchangers, nuclear power plants, and other engineering manufacturing operations all involve high temperatures. These systems have a very big temperature gradient, which has substantial impact on the fluid's transport characteristics. Under such circumstances, using linear Boussinesq approximation taking into account constant thermophysical parameters for ambient liquid become meaningless. Thus, under angled magnetic field joule heating, radiative convection flow of blood-based tetrahybrid nanoliquid in squeezing channel is examined this work.

Governing partial differential equations (PDEs) are produced based on considered physical situation geometry. Resultant Navier–Stokes (NS-E) highly non-linear, coupled in nature. Analytical techniques fail find solutions these resultant NS-equations. The discretized algebraic NS solved by applying Crank–Nicolson numerical scheme through pentadiagonal tridiagonal algorithms. Also, flow fluid effects gives 4th order PDE which needs algorithm solve it. Implementing this numerically is challenging it worthy investigate analyze behavior. Hence, simulated velocity, energy, mass diffusion profiles including engineering quantities interest boundary layer region discussed for different parametric values.
