Thank you Sir! This was an awesome tutorial! (besides that music)
i have a problem when i start the solution . "Update failed for the Solution component in Fluid Flow (CFX). The solver failed with a non-zero exit code of : 2" can you help me ?
you prolly dont give a shit but if you're bored like me atm you can watch pretty much all of the new movies on instaflixxer. I've been streaming with my gf for the last few days =)
@Frederick Maximiliano Definitely, been using instaflixxer for since november myself :D
Sir your video is very helpful for me. Thank you.
Sir....How many timesteps where produced during the process?? Pls reply
i am getting an error while running CFX solver like program exited with return code 1 and no file has been created . Help me please
Step 2- Meshing of stator, you said, "repeat the steps that we did early for stator."
What do you mean by this? Are you reffering to any previous video or you just said it mistakenly, mean you intended to say rotor. Kinldy clarify this.
Thankyou
thanks a lot may you be happy always
I have a problem .After connecting to part in CFX when try to open setup file it's shown Application failed to connect .What can i do in this situation?
Very helpful video . but can you give me an insight about defining timestep? how you defines the timestep/period? and what exactly passing period is?. i looked into cfx help but I still confused . thx
Hi, thanks for the great video! Could you possible make a savonius simulation inside a pipe? and derive power graphs and power coefficient graphs with RPM? That would be a huge help. There is a gap in existing videos!
Where do we find the speed of the turbine?
Hi guys, thanks for the tutorial. My computer was running but showed the follow error: "The ANSYS CFX solver could not be started, or exited with return code 255:
. No results file has been created.", I tried to solve but I didn't find any solution, If you know about that, I will be grateful.
good afternoon, were you able to solve this problem?
Hi, why do you set rotor - basic setting - domain motion on 100 (rev per min)?
I join the issue. Why?
hi i need your help. when i'm setting up interface, the interface side 2 of everything is not showing
Thank you very much for the video.
During the solution in cfx
Show, update failed for the solution in cfx. The solver failed with a non zero or exit code:2
How to resolved this problem
Thank you. According to analysys, my turbine has 15kw power. İt should have 4 kw power maximum😢
Hi I am not able to select those WallRotar as named selection !! Why is it ? Kindly help me
We have to find RPM as output for wind turbine. What data we require as input for CFX?
May i know why my efficiency is more than 100%?
Or any formula suggest?
Very informative video, thanks for the effort.
A small tip: that background music is annoying.
thanks for advise
Hello sir i want to what results and parameters are you getting from this analysis
hello, sir, I've seen your video and I like it, sir I want to know what parametric results you got from this
Do you know the math for electric motors: grinder, drill, blender, wand blender, alternator, home fan, treadmill, washing machine, etc... universal vs dc ? what can you find that's already made in vertical type turbine, ( cylinder hood vent) etc... or can you purchase or make blades for metal circular bases with a shaft . What size shaft is required for rpm to watts to volts to motor size and rpm zone (ie-100-2500 rpm ) or 800 -8000 rpm etc... ?
Thanks for the tutorial..dont mind.. hate the music..
When I do what you did with first meshing (max tet 40 mm), I get an endless wait on volume meshing. Volume meshing never ends. Do you know what should I do ?
Increase your size to 50 mm then you can solve it
How can I optimize my design after the simulation?
how calculate wind mill fan force turque speed and time in solidworks
Great video but when do you get the power out in watts ?
Yes, it is watts
Hey why is your Expression Power is in Joules ? It should be in Watt right ? And why is the RPM unit less ? Kindly reply to this !!
When we use expression we can to choose any units or remove them. Power of the turbine rotor is calculated as P (power) = M (torque)* omega (RPM*pi/30). You can to follow for units or no. Whatever, you get unit - [Watt]
Why -ve RPM ??
help me to get idea about it
If rotation axis of your stuff stand on Z axis, then your blades move right..
You need to put -ve.
Use your right hand rules.
Any similar tutorial in Ansys-Fluent?
Why n = 100 ,not -100 ?
My power between 0 ~ -1 ..... represents what ?
please. thank you so much!
Same doubt for me as well. Did you get correct interpretations of the result?
can you make cfd analysis of vawt helical type with 3 blades ?
Yes we can, you can write your suggestion to email: cfd.intech@gmail.com
Where is interface 2?
sir....ansys application version
...
Pls Comment
hay CFD intech please please please help me please
The music is spooky.
can you make a flapping wing analysis??
You can write your offer on mail: cfd.intech@gmail.com
CFD Intech i have mailed to you, please have a look at it.
hey CFD intech please reply please please
Hello, you can write me on email: cfd.intech@gmail.com
CFD Intech thank you ! sure i will.
Could u send geometry pls 🙏🙏
Hello , can u send me via mail the geometry version please
heyy i already emailed. please check that
Why did you set 100 rev/min?
Rotation speed relates from moment on a shaft (generator + friction losses), which we don't know. So i set random rotation speed. But if you know moment you can calculate your rotation speed - n through expression for power: N = M*pi*n/30.
@@CFDIntech what if i need to derive resultant torque and force on a wind turbine only from a wind of a certain speed? Do i set initial 100rev/min as 0?
@@CFDIntech thanks for your video, by the way
@@arshynmeiirbekov6830 You can use the formula Torque= (Power output/RPM)*(30/pi). Power formula is 0.5*CP*rho*A*v^3; where v is your free stream velocity, A is area swept by the turbine, rho is air density and CP is turbine efficiency. You can define your required torque and then calculate for power.
@@AggarwalPranshu hi, what if I want to find power coefficient and torque?
И здесь тоже. Типа сам ввёл частоту вращения и давай мощность калькуляте) Ветровая турбина же не так работает. Сам частоту вращения ты не задаёшь как в электродвигателе.
можно 6DoF считать подход, но там есть свои нюансы, проще посчитать вращение турбины с разной фиксированной частотой вращения и снять момент. Нагрузка на ЭД + механические потери трения будут создавать момент нагрузки, который и будет определять фактическую скорость вращения турбины. То есть можно построить моментную характеристику турбины n - M (частота вращения/момент на валу) затем посчитать предполагаемую нагрузку потреблямой электрической мощности + механические потери трения ( на подшипники и тд), после этого на графике моментной характеристики турбины, можно найти точку момента на валу которая и будет соответствовать определенной частоте вращения.
@@CFDIntech Скорость ветра 5 м/с. Как узнать скорость ветра и крутящий момент на валу, используя Ваш подход? То что Вы написали выше ясно только Вам.
where is fuckin named selection of second part ?
#HELP, #PLEASE :(. First, Thank you for this amazing tutorial, I have a graduation project discussion in 4 days, but I still have some problems doing same steps! Can you please explain in more details the rest of the meshing process! I tried to do it by myself, but I am not sure if it is correct 100%? + why when I start interring the data in the CFX setup section, it crashes and the CFX closes suddenly :((( ☹
