problem in plotting the velocity profile

Respected sir i have attched one picture here , likethis picture i want to plot velocity(u) vs y plot my formula for velocity profile is below whatever I have done in Matlab code I am writing below the formulae

U = 1./mu.*(t_o.*(y-delta)+4.*alpha.*sqrt(t_o.*t_e).*exp(- alpha./(2.*delta))+t_e.*alpha.*(1-exp(-y./alpha)))

   t_o=100 

t_e=150 

mu=0.3 

delta=0.6

 alpha values are 0.1,0.2,0.3,0.3,0.4,-0.2,-0.5

Answer 1

[KSSV]

alpha = [0.1,0.2,0.3,0.3,0.4,-0.2,-0.5] ;
t_o=100 ;
t_e=150 ;
mu=0.3 ;
delta=0.6 ;
y = linspace(0,1) ;
figure
hold on
for i = 1:length(alpha)
    U = 1/mu*(t_o.*(y-delta)+4*alpha(i)*sqrt(t_o*t_e).*exp(-alpha(i)/(2*delta))+t_e*alpha(i).*(1-exp(-y/alpha(i)))) ;
    plot(y,U)
end

graphs are not coming expoential. should i non dimensionlise the equation

[KSSV]

Check your formula....values...

[Souvick roy]

Sir sorry for wrong formula. i have editted formula

Formula

values are

delta=0.3

gamma=0.1

lambda values 0.01, 0.02 and 0.03 for threee velocity plot

velocity plot should come

please help me sir

Dude..you have the code.....you need to edit the formula and run it. By the way the updated formula doesn't have alpha invovled.

[Souvick roy]

sir i rename alpha by lamda

[KSSV]

YOu be sure of the formula, image and values associated with it.....the image says omething..it has beta and alpha also.
