The physical impact of blowing, Soret and Dufour over an unsteady stretching surface immersed in a porous medium in the presence of ternary nanofluid

This study discusses the thermal and mass dispersal of ternary unsteady nanofluid flow in the existence of Soret and Dufour effects over a stretched surface with the Stefan blowing (SB) effect in porous media. The blowing effect is created by a large number of molecules or nanoscale particles moving from one point to another. SB is a mass transfer of species application that gives the notion of the blowing effect, as well as the Soret and Dufour effects, which are also being considered in the current study. The governing equations that pose the problem are solved using appropriate similarity variables and then translated into ordinary differential equations. Runge-Kutta-Fehlberg 45 and the shooting process are used to solve the reduced equations. The effect of the different dimensionless restrictions on the relevant profiles is visually depicted. According to the analysis, the rise in the porosity constraint will decline the velocity of the fluid. The SB parameter directly influences velocity, thermal, and concentration profiles. The Soret constraint increases concentration, whereas the Schmidt number has the opposite effect. With the addition of solid volume fraction, the rate of mass transmission and surface drag force reduces while the rate of heat dispersion increases.

Automated summary

This study discusses the thermal and mass dispersal of ternary unsteady nanofluid flow in the presence of Soret and Dufour effects over a stretched surface with the Stefan blowing (SB) effect in porous media. The analysis shows that an increase in the porosity constraint decreases the fluid velocity, while the SB parameter directly influences velocity, thermal, and concentration profiles. Additionally, the Soret constraint increases concentration, whereas the Schmidt number has the opposite effect.
