Condensation of Humid Air using Ansys Fluent

[@jdh8138]

Please could you reupload the google drive file? Thank you.

[@cahyaamalinadhi4327]

Hi! nice tutorials I want to see the model, however, I cannot access the gdrive link.

[@msaisantoshpavankumar9749]

The g drive link is not working. Is it possible to share again

[@antonydavila6372]

Thank bro, Why do you put 1 phase -> mixture template if you say 1 phase -> water-liquid?, minute 2:05.

The file shared in the description does not exist. Can you please re-upload the file?

[@mariosalazar5298]

hello thanks for your video, im trying to run a simulation with species transport an multiphase model as yours for a hvac system, but mine have recirculation boundaries and is not working, are you familiar with this configuration? my objetive is to obtain the temperature of the room aconditionated and also the relative humidity reached with the hvac working

Hi Sir, Above mentioned drive link to download cas file is not working. Can you please provide me link to download cas file.

hi. thanks but i dont see temperature settings at inlet ?

[@johndoe-ow2ns]

I don't understand why you need to define a UDF for the saturation temperature. Why doesn't ANSYS know how to deal with this by itself?

[@kevinjulian716]

Hello, kind Sir. Is there any chance that I can get your .cas file ? I would like to simulate humid air condensation too, but I'm currently experiencing difficulty even though I have finished watching video. Thank you very much, Sir.

Thanks for your nice video. I have a small question. Can I simulate the following problem with your setting? (Still two phases? or use three phases: air, vapor, and liquid? And the same UDF?) A bottle with half of liquid water and half of air. The temperature on the bottom of the bottle is higher than 100 C (say 200 C) as a heater and the top cover is 10 C as a condenser. I think the simulation result would be: liquid water starts to evaporate -> the vapor goes up into the air -> as the vapor reaches the top of the bottle (condenser), it becomes liquid water and drops down. Thank you for your help!

[@shavantechnology3472]

Air and Vapor combinedly belong to one phase (gasesous) which is multispecies. YES u can use the udf

[@liyinglau2275]

Hi there, have you successfully simulate the case? i have the similar condition, but the simulation shows floating point error, can you share more about your case? thank you!

[@kishtanmusic]

How to calculate saturation temperature with respected to the pressure in this equation which is given in the udf ?

[@spring6735]

Hallo, thank you for this tutorial! I just didn't understand how you modeled the condensation temperature with the UDF, which physical law did you referred to? Also, it is not possible to access to your link in google drive.

[@shavantechnology3472]

It is saturation pressure vs temperature antoine equation

@@shavantechnology3472 hi shavan.. thank you for the good tutorial.. one question over the constants A,B,C used in Antoine equ as most of the paper tells it is 8.14,1810.94,244.5 but the values use by you are different.can you pls provide the link from where you have refered.

@@skinfoconsultancy3787 Hi bro did you get the answer yet?

[@房子陽]

@@skinfoconsultancy3787 may be the reason for the unit conversion (K->C, mmHg->kPa)

[@johndoe-ow2ns]

Is there a mistake in his udf file? On line 15 he defines p_wv but on the next two lines he writes p-wv. Shouldn't this also be p_wv? I find it hard to believe that Fluent doesn't know the saturation temperature of water and that a udf is necessary to define it.

[@nikhilraj7301]

sir can you please share the link again this link is not opening .

[@umairatulafiqah6534]

hello! very good tutorial! is it possible if i see the model?

[@pistonengines7932]

Dear sir, can we obtain/calculate film thickness as a result of this simulation? If the answer is yes, could your explain how to do it?

[@shavantechnology3472]

Using Eulerian Wall Film

[@weili9556]

It has driven me crazy, the UDF is not working, could anybody please help?

[@kayahanpancar6010]

could you find the correct UDF?

[@kitter1222]

Sir thank you very much for excellent tutorial. Kindly share dimensions of the model

[@venkatpuneeth7141]

Explanation and presentation of the video has a lot of scope for improvement.

[@sherlinarahma3626]

sir can you help me about your tutorial? because this is my thesis topic

[@prof.amaya-ccsu6349]

Do you have any experience on condensation in free convection?

[@shavantechnology3472]

Yes I have , mail id : [e-mail]

[@ivantheengineer9422]

and where is a condensation? sorry, but your model is incorrect

[@raveeshg4286]

Thank you very much.
