how to find pressure coefficient and drag coefficient

Yohan Prasetya Feb 11, 2015 6:18 AM

Can you help me, for teach how to look for the pressure coefficient, drag coefficient and lift coefficient ??

I use an external flow in circular cylinder with a diameter of 100mm. and I use a 2D computational domain.

please note I use the Re 1 x 10 ^ 3 and 10 ^ 6

I want to find a graph Cp (pressure coefficient), Cd and Cl

I found a picture of several journals, and I want to make a chart of CP, Cd, and Cl as the graphic images, here I include graphics ....

I am very grateful for the support of teaching for me

where are you getting hung up?

this is covered in the tutorials and verification problems

you can create an equation goal to output the information and then use a parametric sweep to actually run through the tests

  I get a picture of pressure coefficient of the journal made by Islamic toukir
  
  I want to know is how I found the CP (pressure coefficient) corresponding
  
  I have found the goal drag force and lift force, static pressure, velocity.
  
  but to find the CP, I still find it difficult, if you can help show the steps to find the CP and the graph of x, y plot of Cp than the angle as shown in the picture ....
  
  I am very grateful for the help ...

    can't you use the equation here? Pressure coefficient - Wikipedia, the free encyclopedia
    
    and then run simulations modifying angle of attack using a parametric study?
