Ansys V190 Acoustic Native Features : Muffler Transmission loss calculation

Ansys V190 Acoustic Analysis procedure to calculate Muffler Transmission loss over a frequency range.

You may ask questions here, if any.

[@adityashrivastava8498]

sir, what is this surface velocity of? Isn't 0.025 too less?

[@mohdshadab-ug2ut]

thanks for very helpful tutorial, i have generator room to make it acoustic analysis, i will pay for that if you guide me...

[@leejiajianstudent5449]

Hi, Sir can you make a video to show how to do the simulation of the sound absorption coefficient of Micro Perforated Panel?

[@riziyamaalisagavit4449]

Hello sir,if in example if we dont have long constant tube instead we have 2 different tubes for inlet and outlet how to select inlet and outlet port

[@ricardomaia5375]

why did you assume the same sound velocity to the foam and air?

[@chetan9gaonkar]

Hello sir. Found this video very useful. I wanted to know if you have any tutorials for complex muffler analysis (considering the mean flow).

[@SanthoshKumar-ge9sq]

Mean flow can be accounted. An Example: ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v201/en/ans_vm/Hlp_V_VM297.html

@@SanthoshKumar-ge9sq thank you for your kind reply sir. However this link is not opening as it requires customer login I'd. Can you please email me this tutorial in pdf form on [e-mail]. Thank you in advance

Sir, why is the frequency taken in range of 1000-2000 Hz? And what is the criteria for taking frequency in a muffler analysis?

[@loctran2618]

What is the name and version of the extension used in the video?

[@rajatkasliwal6271]

Hello sir, this was a simple muffler problem for TL. I want to perform the same for complex geometry mufflers which has partitions, baffles & extended perforated pipes, can you please share any tutorial on the same??.

[@nkatiyar_IITK]

See comsol Multiphysic

@@nkatiyar_IITK Thanks for reply, but i want to do this in ANSYS only. Can you share how to proceed.

@@rajatkasliwal6271 I am having the same problem Rajat. Do reply if you got to learn how to do it

[@chiragkumargohil9917]

Sir, from where I can get geometry??

[@SanthoshKumar-ge9sq]

It can be downloaded from Ansys customer portal.

[@SanthoshKumar-ge9sq]

No, procedure for TL calculations of plates is slightly different. An example is provided in Ansys Mechanical Acoustics Training course material.

Would you please upload the used extension file

[@adityashrivastava8498]

Sir, one question. If we use foam, won't it get burnt because of high exhaust temperature???
