Numerical analysis of conduction heat transfer flow and the viscosity of the fluid passing through a flat channel using AGM and Flexpde software

In this paper, we investigate changes in temperature and velocity using various flow parameters and study the effects of viscosity and conduction heat transfer in a vertical channel. First, we make the fluid momentum and energy equations dimensionless by adding the corresponding boundary condition. Then, we perform the associated analytical analysis using AGM and FEM and plot the relevant graphs. According to the analysis results, the higher the Prandtl number and the lower the value of s, the larger the heat transfer. In addition, the temperature increase with an increase in the distance from y=۰ to y=h given the Eckert number (viscous dissipation). According to other graphs, an increase in the Gre parameter first increases the velocity. The results obtained in the graphs for these methods and their comparisons with NUM indicates their acceptability and the appropriateness of the work. The same results show that velocity and temperature increase with an increase in thermal conductivity.
