Broo... One doubt... 15:12 .. Here (in animation) in the converging section the pressure is decreasing ( red to yellow ) from inlet to the throat .. ... But at first (1:14) in the problem it is saying that the pressure in the converging section increases Any idea ..
Hey Sonu, In converging section from inlet to throat, the pressure reduces and velocity increases. No doubt in that. It happens as per the Bernoulli principle. I saw that in the video he said differently. I think he messed up that part
1:15 You mixed up pressure and flow velocity in the convergent nozzle. Nozzle section: Flow velocity v increase while pressure decrease. In fact in a laval nozzle flow velocity is increasing all the time while pressure is decreasing...
Good presentation Professor, please check your third PPT you mentioned that pressure increases and velocity decreases in the converging part of CD nozzle, which require correction. In the CD nozzle from inlet to outlet pressure decreases and velocity increases
KANNAN K Sir is CD nozzle the pressure increases in inlet comparing the exit divergent part !! what ever I have mentioned in ppt is right !! It's the core theory of C-D nozzle !!
Hello sir, If the flow is subsonic at the inlet of convergent part and the flow velocity decreases in the convergent part.. Then according to this, sonic condition can not be achieved at the throat. Think about this sir....
If flow is subsonic:- In convergent duct- flow accelerates. in divergent duct- flow decelerates. If flow is supersonic:- In convergent duct- flow decelerates in divergent duct- flow accelerates.
@Nir Modan don't apply the Boundary condition on to outlet.Since the outlet pressure is subjected to atmosphere,it should be given as zero to initiate CFD packages to compute and simulate the realistic analysis
thanks for the tutorial of yours first of all. Secondly, I have master degree thesis and wanna clear up it to you. Could you help me out for doing it in Anysis ? Wait for your support. Thanks a lot.
Hey, thank you for the neat video and explanation. Let's say I want to simulate a situation like this...but only for a nozzle which gives out drops or say a printhead nozzle. How could I change the settings and provide a similar stream line ?
That such could help me, I'm doing a thesis of a micro sprinkler irrigation and I need to simulate the fluid as it leaves the nozzle .. so you see has any tutorial or something that you can guide me. It would appreciate enough.
sir,i need a help in defining the length of the nozzle part. Is there are calculations available to find the overall length or the inlet length of the nozzle.
Can you plz let me know how to calculate boundary conditions (inlet and outlet) for given chamber pressure (P0) and nozzle expansion ratio (AR)? Need to get Normal Shock in it. Appreciate your help.
I'm trying to make a non-premixed combustion in Fluent, I will use liquid ethanol (C2H5OH) and liquid oxygen (O2). But I don't know how put the mol fraction from ethanol in the boundary tab to do PDF table creation. Do you know how to do this?
Hello, I have made geometry for 3d titling nozzle assembly. Have to do pressure and flow analysis at each point. what boundary condition i should put and how to solve it . Can i send u geometry of my problem so that you can tell the solution . Regards.
Please, can you help me to simulate the condensation process inter the microchannels. Especially the phase change term is very urgent. thank you in advance
Nir Modan if u reduce the pressure than then inlet u get reverse shocks, As per Continuity equation -The mass flow Inlet is same at the outlet and We consider the pressure at Outlet as Pressure farfield or Pressure = 0 to Simulate the exact atmospheric condition

doppeldeluxe Instead of giving velocity inlet 442 m/s I have used 3bar pressure inlet , both are same!!

no the pressure decreases in the whole process as the velocity keeps on increasing

Hi bro have some doubt 7659984506 wts up..?
Great tutorial. Thank you
Thanks for the video. Very helpful.
very nice tutorial sir!!.. Cud have been a li'l slower!!... nonetheless, very good n helpful!!.. Gracias!!
very nice and interesting video! thank yo very much sir!
Sir can you explain in detail regarding having negative pressure and what is operating pressure in this simiulation.
Pressure increase and velocity decreases in convergent section during subsonic flow. You have to correct it. A blunder.
Thanks for the tutorial
thank you so much you saved my life
Hi
Excelent explanation sir!
Good of you to put in the time to put something online. Any future videos, could you remove the mouse clicking noise, as its very distracting.
Many many thanks. What is NPR(nozzle pressure ratio)? and What is NPR in this simulation?
Thanks so much sir. It was very useful
I don't understand the part of Monitor . I have the version new 19.2

THANK YOU SO MUCH SIR
Is there anyway you could model the same nozzle exhausting to the atmosphere and upload a video? I've been trying but not getting the results.
That such could help me, I'm doing a thesis of a micro sprinkler irrigation and I need to simulate the fluid as it leaves the nozzle .. so you see has any tutorial or something that you can guide me. It would appreciate enough.
why as a result of plot at velocity there is no mach number?
Hello, Thanks for the nice video. Please can you let us know what is the operating pressure?
Venkata Ravindra M V I have applied 3 bars u can try it wit 1 bar also
Hello, Why did you choose Density Based as solver ?
dear sir, if flow within a nozzle is symmetric about its axis, half of the model is sufficient with symmetry boundary. isn't it ?
The Symmetry will not give exact approximation !! You can simulate and check it
+CADD MASTER i understand. thank you.
Thanks a lot!
Sir, please make a tutorial on SLOSHING OF LIQUID IN A TANK in FLUENT. i need it for m project.
Sometime I think how the pressure is going the negative value pls explain it

Could you please help me,i didn't get mapped face meshing, simple i am getting face meshing.please help me
Thank you so much.......
Am i mistaken, or did he run the simulation in 2 dimesions. If so, why?
2d is easier for computation
very helpful....thanks

how is that going?
Could you also show the Temperature distribution

Hi, can you analyze the flow of the plate heat exchanger ?
WHY IS PRESSURE NEGATIVE? :(
Thank u
Nice tutorial, better give more reasoning for options selecting then it will be highly appreciated
Please, can you help me to simulate the condensation process inter the microchannels. Especially the phase change term is very urgent.
thank you in advance
Where could I find the program
Can this be done on student version of Ansys
i'm trying to make a shockwave in the divergent part. how should i do that? i tried to raise the outlet pressure but nothing happend.
Nir Modan if u reduce the pressure than then inlet u get reverse shocks,
As per Continuity equation -The mass flow Inlet is same at the outlet and We consider the pressure at Outlet as Pressure farfield or Pressure = 0 to Simulate the exact atmospheric condition
Is it possible to have paper for this project? It would be very much helpful for my upcoming ansys validation!

why do you have a 2,82 Mach and later you got only 609,4 m/s? the math is not right.. you should get close to 958 m/s.. Am I wrong?
Speed of sound is higher at higher temps.
there is no such thing as mapped face mesh in mine
ok, in new versiin of ansys you need to use face meshing + sizings to get a structured mesh
click from the mouse can be heard more clearly than your voice
Not even audible on home theatre
Very very low audio
please explain properly because we want to learn from basics. very bad explaination I am getting very bad words but I am controlling you.............
Not specified
Not clear voice
u made it too fast
I've spent 5 hours😂
