hi . i have a problem in validating . im working on a cyclone .


as u see i used this paper for validation . in the tangential velocity the plot is kinda sinusoidal and the picture under it shows tangetial velocity for different length of outlets and its really very different from the other plot .

whats right ???

my plots are like the first (sinusoidal) .

it seems papers have exported data to excel or something and used the absolute value . because this is the only difference in my result and other papers . what do you think ??? please share your ideas with me . thanks
