I am trying to plot the 'variation of Nusselt number vs distance' for my project.
According to the problem statement, there is a convective flow inside a 2D square , whose sides are maintained at different temperatures. The bottom surface is maintained at a higher temperature as compared to the side surfaces. The liquid inside is initially at rest, until convection prevails.
I am required to plot the variation of local Nusselt number along the bottom and side walls with respect to the wall distances. But we cannot put an expression for local Nusselt number for plotting the graph. So what expression must we write in place of Local Nusselt number (to be ploted along y-axis) in order to obtain the required plot (as per the attached file) ?
Someone please help...!
