3. (6 points) Implement the following limiters in your code and solve problem 2 (each case) again. Assess the effect of each limiter on the second (or higher) order schemes (LW and WKL). Show plots comparing the numerical solutions obtained with and without the limiter; include analytical solutions on the same plots. (a) Van Leer limiter: V(r) = (r + IrD/(1+r) (b) min-mod limiter: V(r) = min-mod(r, 1) (c) 'superbee' limiter: V(r) = max(0, min(2 r, 1), min(r. 2) 3.
