HEAT TRANSFER IN COUPLE STRESS TWO-FLUID FLOW MODEL: EFFECTS OF MODIFIED HEAT FLUX, ELECTROMAGNETIC FORCE, AND UNEVEN HEAT SOURCE/SINK

The aim of the present investigation is to study the variations due to uneven heat flux and an electromagnetic field on the couple stress fluid flow of a binary mixture traveling through a stretched cylindrical surface with developed heat flux. The partial differential equations governing the fluid transport system are derived into a set of ordinary differential equations using suitable nondimensional parameters and similarity transformations, which could then be computationally solved using the Runge-Kutta Fehlberg method. The main aspect of the current problem is that it discusses the entire scenario in terms of the liquid and dust phases. Using the MATLAB code, a graphical representation of the relevant parameters is obtained. The results were carried out for our system, and it reveals that the velocity and thermal gradient of both the phases of fluid and dust behave in an opposite trend for rising mass concentration, where the curvature parameter makes the rise in the same manner. Furthermore, the thermal transport profiles for both phases decline for the rising thermal relaxation parameters.
