Heat and mass transfer analysis of MWCNT-kerosene nanofluid flow over a wedge with thermal radiation

A comparison between the unsteady and steady magnetohydrodynamics Tiwari-Das model Williamson nanofluid flow through a wedge occupied by carbon nanotubes of multiwalled type nanoparticles and kerosene as base fluid is presented in this analysis. A suitable similarity variable technique is adopted to transmute the governing partial differential equations into a set of nonlinear ordinary differential equations (ODEs). To solve these ODEs together along with boundary conditions, we have utilized finite element analysis. The behavior of concentration, temperature, and velocity sketches for diverse values of the pertinent parameters is plotted through graphs. The impact on the above parameters on the rates of velocity, heat, and concentration is also evaluated and depicted through tables. It is noted that as the values of nanoparticle volume fraction parameter rises, the rates of temperature increase in both the unsteady and steady cases.

Automated summary

This analysis compares the flow of Williamson nanofluid through a wedge occupied by carbon nanotubes with multiwalled nanoparticles in unsteady and steady magnetohydrodynamics Tiwari-Das model, using kerosene as the base fluid. Nonlinear ordinary differential equations are obtained from the governing partial differential equations using a similarity variable technique and are solved using finite element analysis, showing the impact of various pertinent parameters on velocity, heat, and concentration rates through graphs and tables. It is observed that the temperature increases as the nanoparticle volume fraction parameter rises in both unsteady and steady cases.
