มุมมอง 14K5 ปีที่แล้ว
In this tutorial i just show you how to see the model of the airflow passing through the wing at the maximum AOA (Angle of Attack) using ANSYS Fluent at the last Steps (Result). Dont Forget to LIKE and SUBSCRIBE this Video.. the link of the other steps using ANSYS fluent that you may wanna look at : -th-cam.com/video/lvIrLfNtQko/w-d-xo.html -th-cam.com/video/UBdrg6aSb2A/w-d-xo.html

In this tutorial video, i want to show you how to calculate propeller Thrust Force using cfd ANSYS 19.1. The model of the propeller was made using SOLIDWORK software and the rotation of the propeller = 6000 RPM with the flow velocity = 15 m/s.. Part 2 : th-cam.com/video/9xnubvVsvyM/w-d-xo.html

In this tutorial, im using the wing model that made using SOLIDWORK Software and the Angle of Attack of the wing is 10 degree. Moreover, the flow velocity is 15 m/s. part 2: th-cam.com/video/UBdrg6aSb2A/w-d-xo.html
You guys help us become better engineer
My mesh propeller mesh looks bad what should i do
By far the best tutorial, thank you!
hey what is dimensons of your propeller??? imean the diamater and chord?
Thank you, very much recommend
Thank you for the help.
thanks
0:44 why is gravity in y direction???? shouldnt it be in x or z direction?!
This seems to be a drone propeller, so gravity works along he rotational axis.
Hi please can you do step by step exhaust fan simulation and Fan rotation animation for air
If you could be able to share the link to the geometry it would be great
Why is the thrust so low? Isn't it normally in the range of 500-600 N for a regular drone blade?
The speed of advance is too high for the RPM of the propeller. Thrust comes from the fluid mass acceleration through the propeller disk. If the inlet velocity is too high, the blades are unable to increase fluid speed. Thats all a matter of a wrong design for the choosen conditions. Thrust can be increased in a several ways, the most obvious being increasing RPMs. But don't forget that linear blade tips speed must always stay below the speed of sound.
Where did he shown the thrust man?gimme the timestamp
wich software use with version name plz
merci beacoup
Thanks a Looot the videos helped!!!
There is no lift calculation....
do you have propeller file 15x4? can give me?
Where did you get the speed 15 m/s at a certain rpm? From manufacturer data?
How i get torque? Besides, that Force value is straightaway in Newtons ?
Multiply the force with radii
where is part 1
hi can you please do the same thing in openfoam
Hello, Thanks for this video. I am studying the flow around a 3D wing and would like help with the reference values to be specified in Ansys Fluent. I know the area is the top surface of the wing, the length is that of the chord. But my problem is that the chord is not constant all the way down the wing (the chord at the root is bigger than the salmon one). How can I specify the chord in this case, please ?
i use ansys 2018. no option for force. only drag, lift and moment
Thanks for interesting tutorial... I have an question, why do you put inlet velocity(15m/s)? not just set it pressure outlet?
same question here!!..when you have RPM why inlet velocity.. and how to find that inlet velocity with testing physically
@@UnfinishedEngineer I found out how it is. you are using pitch of the propeller means how much it travels so you have the rpm that you desire to calculate. [rpm*pitch(inches)]/[60 seconds*100]
Please give the diameter and pitch of the propeller used?. Thanks and V.good
Guys how can we calculate for moving angle of attack like -5 to 20 ?
Hi Giovanni. I am also doing project and want to change angle of attacks. please Guide me in this regard. Thanks in Advance
@@usmanhaiderawan2739 I'll work on it soon if i solve i will guide u
I have a question in fluent, did you set the "propeller" as Stationary Wall or as Moving Wall? Besides, would you know why when I see the streamlines in the cfd-post I don't see lines behind the Rotating Body? It could be due to a small Static Domain or Rotating Domain? It's strange because the thrust has a logical value... Thanks!!!
hey antonio, im also currently having this problem. My streamlines hit the top of the rotating domain and then stop, they then exit at the bottom of the rotating domain but I am not seeing any streamlines inside the rotating domain. Did you find a solution for this? Cheers
@@samdougherty5559 same problem here, still trying to find a solution!
@@samdougherty5559 i think your velocity direction is not correct
Can I calculate drag force for boat in same way?
Please guide me about sump model analysis
i get the" run cannot be started until validation issues are resolved " error in the calculation stage, what should i do ?
Same here
Could you please provide the propeller geometry?
Can you please upload the propeller as Geometry import. Thanks in advance <3
How to do acoustic analysis of propeller?
Before that how to design that propeller!???
You can design propeller in onshape Which is cloud bases CAD software Or Solidwork Or Fusion 360
@@MindlyMusic bro can you help me pls, genuine help needed pls fast reply
Can you give your email ID?
Hi there, where did you get the propeller CAD? Thank you
quick question why did u use fluent fluid flow and not the other option available
when simulating a drone, is it necessary to simulate all rotors in the same domain or they can be in separated simulations? thanks
you can simulate just one and use periodic boundaries.
Do you know how can we get the drag force. I am trying use the same way to get the thrust force, and also caculate the drag fore with the force report, Drag. But these two force are totally same? DO you know How to get the correct drag force?
When calculating Thust force, the result is the NET force induced by the propeller, hence drag is already taken into account. From my point of view, an important value that's always omited in all of those tutorials is the propeller Torque. Torque is a main design requirement as the motor/engine selection will directly depend on it.
I found your video very helpful but I am stuck with a problem: for some reason the fluid goes around the disk that surrounds the propeller instead of going though it. Can you tell we what am I doing wrong?
Hello, same problem here, did you find a solution?
@@ninamoello Yes. You need to couple adjacent surfaces as "interface".
@@mr.hollywood835 It seems that the software does it automatically (Ansys 2021 R1), I already have a mesh interface between the inside and outside parts of the cylinder.
I got it, just need to define the geometry as only one part of 3 bodies, not 3 parts.
@@aa54785 Hi, how can I help?
Hi. What did your maximum skewness end up being in your mesh? Thank you for the video!
In mesh interface, I also have "propeller-contact-region-src" I followed your steps but I dont know why this appeared. Could you please tell me, how can I solve?
Hi. When i do the first enclosure, part of my propeller disappears. Can you help me? Thanks!
NOTE SUPPRESSED:YES
can u pls provide the propeller
yes
Where is the Lift Force though Sir? THANKS!
Hello Sir! As I start the simulation it displays "floating point exception". what does that mean? Thank you so much your reply would mean a lot!
Thank you for tutorial it helped me alot but I am not getting the expected result contour pressure of my propeller is completely opposite low pressure under blade and high pressure above blade. Can you please help me.
Are you rotating it in the right direction?
@@christianlabanca5377 can I get your mail id plz :). ?
@@abhilashm6711 Yeah sure. It's clabanca7@gmail.com If you have any questions we can try and solve them
the rotating direction is not correct
Hello, nice tutorial! Please can you explain about the rotational speed, is it rotating clockwise or counterclockwise from the arrow of the Y-axis?
cw or ccw is obvious by looking at the blade
Hello can you tell me what is that error that you are getting when you begin calculation "mesh interface overlaps for interface zone"
Your meshing isn't proper
Hello! Is the shroud's surface area supposed to be used for reference? because as far as what I found on a few other websites, they had mentioned the wetted surface area of the wing. Please do let me know!
How was the flow velocity of 15m/s determined?
yeah .thats what ı really wanna understand
@@mehmetfurkankoprn8655 By advance ratio.
Then , I think it was known in advance through experimental test, what would be the speed at a certain rpm?
