https://drive.google.com/file/d/1DwqoZGwEvt6-PbivGHCHpd4HNr1iqdHF/view?usp=sharing
AIM:
To determine the pipe flow simulation with an inlet as Renolds number 100,1000,10000.
FLUID AND DIMENTION OF THE PIPE:
FLUID:Air;
DIMENTION OF THE PIPE:
Outer diameter of the pipe =60mm;
Inner diameter of the pipe=58mm;
Length of the pipe=2000mm;
At 20 degree celsius nu for air is 15.06*10^-6;
Renolds number variation=100,1000,10000;
CALCULATION:
Re=(u*d)/nu
u=(Re*nu)/d;
u=(100*15.06*10^-6)/0.058;
u=0.02596m/s;
PROCEDURE:
- Select the sketch in front plane draw circle of 30mm radius.
- By using extrude option extrude the cicrcle upto 2000mm.
- In order to make the pipe to hollow use the shell option of thickness 1mm.
- Skektch the line probe from exit end of pipe of 100mm,200mm,300mm from the exit end of the pipe.
- In order to achieve the fluid flow the pipe is in closed condition and so using the lid on both side os pipe.
- And then select the fluid(air) and set up the boundary condition Inlet condition=0.02596m/s; Outlet condition=1 bar; For wall=real wall;
- Select either as automatic or manual mesh and run the design.
- In order to view the flow the pipe get cut and transparency
- By select the parametric study apply the different velocity where it is calculated from Reynold\'s number
And run the flow design it give that the velocity flow in each of an individual line probe as well as combined three line probe.
RESULT OF THE EXPERIMENT:
Cut plot 1:For Renolds number 100
Cut plot 2:For Renolds number=1000
Cut plot 3:For Renolds number=10000
NORMALISED VELOCITY PROFILE:
Line probe 1:first line from exit end(100mm from exit of the pipe)
Line probe 2:second line from exit end(200mm from the exit end of the pipe)
Line probe 3:Third line from exit end (300mm from the exit end of the pipe)
Comparision of all the three line probe :
What I Learn:
From this challange I know how to design the pipe with varing inlet renolds number and the velcity distribution in that pipe.
CONCLUSION:
Finally determine the pipe flow simulation with inlet as renolds number as 100,1000,10000
