$4.$ Problem Description $2$

The problem considers the flow around an airfoil $($NACA $0015)$ angle of attack four degree and a free stream Mach number of $\backslash (1\mathrm{.}3(\backslash$mathrm$\{$M$\}=1\mathrm{.}3)\backslash ).$ the flow is transonic, and has a fairly strong shock near the mid chord $\backslash ((\backslash$mathrm$\{$x$\}/\backslash$mathrm$\{$c$\}=0\mathrm{.}4)\backslash )$ on the upper $($suction$)$ side. The chord length is lm$.$ the geometry of the airfoil is shown blow. Show the contour of vector, velocity, pressure distribution and $\backslash ($ x y $\backslash )$ plots.

The problem considers the flow around an airfoil $($NACA $0015)$ angle of attack four degree and a

free stream Mach number of $1\mathrm{.}3($M$=1\mathrm{.}3).$ the flow is transonic, and has a fairly strong shock near

the mid chord $($x$//$c$=0\mathrm{.}4)$ on the upper $($suction$)$ side. The chord length is lm$.$ the geometry of the

airfoil is shown blow. Show the contour of vector, velocity, pressure distribution and xy plots.
