Disign of the silencer for a .50 caliber rifle in Ansys R17.2

Shooting results of the finished prototype in .50 caliber: sound level at a distance of 1 meter equals 142-145 decibels. This is at the sound level of a shot from a 308 caliber rifle with a silencer of a well-known foreign brand.
The inspection also took place at night.
The flash of this sample is completely absent.
The result of testing the finished sample can be seen here: • Супресор для рушниці к...

доброго дня! Не могли б ви мені допомогти з граничними умовами?? У вас є приклад? Мені потрібно розрахувати свою модель з глушником і дульним гальмом в ANSYS, але я працюю в solidworks і не можу цього зробити. дуже прошу!!!

Шукай в интернете статьи из переодического журнала "техническая механика", Харькив. Там цикл статей про разработку глушников с 2012 по 2020 год. Или в комментарии напиши якiй у тэбе e-mail. Я тоби пришлю со своего e-mail ссылку на загрузку архива статей по глушникам - с моего google drive, Гугле-диска.

@@viktorural3399 так мне нужен именно расчет в этой программе, а не статьи в журнале. у меня новая конструкция, ее нужно "продуть". сам пытался разобраться в этой программе, не получилось(

@@ДмитрийДейнека-ъ1н там в статьях есть готовые, гарные образцы глушников для ПК, свд, пкм и т.д. Уже испытанные и доработанные. И в одной статье есть полное описание техпроцесса як зробити глушник з титану, все, от режимов сварки wig(так в Немечине называют tig) до углов заточки резца для нарезания резьбы на станке для глушника.

Is this ANSYS Computational Fluid Dynamics software the best solution you have found for these tests? I am considering Solidworks as a starting point, but also open to other software that is better. What temperature are you inputting for your propellant gases? Thank you for sharing your content!

[@100000ukr]

pls check final result in real build-ed suppressor month ago on my KZbin channel. also i have temperature simulation too.

[@aus71383]

I saw the .50 test - looks and sounds very effective. When you are creating the simulation in the software, what temperature do you input as your parameter for the software to calculate expansion rate, flow rate, et cetera? The combustion temperature of propellant, absorption of heat into the barrel and cartridge casing, cooling as the gas expands - leads to a complex calculation with a lot of variability. It appears based on your results that the temperature you input into your software was less than or equal to 800 Celsius - how did you come up with that temperature initially?

[@100000ukr]

It's not the temperature. This is the velocity of the gases inside and outside the suppressor. Look carefully, there are indicated the speed in meters per second. Yes, there are complex calculations of many factors. In order to count all the computer runs continuously for several days.

[@aus71383]

I see the meters/second clearly now - my question about the temperature of the propellant gases remains unanswered. Thank you for your time and for sharing your results.

[@100000ukr]

The calculation of the temperature is formed by setting the initial parameters for the combustion of gunpowder in a given volume of the chamber. I deliberately do not publish this information here.

I think guns are cool, not only their technology, but their effects, destructive and intimidating power and how these are pushed further by competition, persuasion and fear since the dawn of mankind. Ballistics evolved with us, from throwing sticks to fully automatic rifles. Should I feel bad for liking things that kill? Do you feel bad for developing such technologies, even if that's what you like doing?
